Les acrochordons sont des excroissances cutanées bénignes courantes qui apparaissent fréquemment sur les chiens âgés. Bien qu'inoffensives, ces excroissances peuvent parfois inquiéter les propriétaires d'animaux en raison de leur apparence et de la possibilité de survenues multiples. Dans cet article, nous allons découvrir ce que sont les acrochordons, pourquoi ils se développent, comment ils sont diagnostiqués et les options de traitement disponibles.
Que sont les acrochordons chez les chiens ?
Les acrochordons sont de petites excroissances bénignes qui peuvent apparaître n'importe où sur le corps d'un chien. Ils ressemblent souvent à des extensions en forme de tige et peuvent avoir une surface semblable à une verrue. Bien que ces excroissances puissent affecter les chiens de toutes les races, les races plus grandes ont tendance à être plus à risque. Les acrochordons ne provoquent généralement pas d'inconfort ou de douleur, sauf s'ils sont irrités ou blessés.
Causes des acrochordons chez les chiens
Bien que la cause exacte des acrochordons ne soit pas entièrement comprise, plusieurs facteurs contribuent à leur développement, en particulier chez les chiens âgés. Ces facteurs comprennent :
- Vieillissement:À mesure que les chiens vieillissent, leur peau subit des changements, ce qui rend les chiens plus âgés plus susceptibles de développer des acrochordons.
- Genetics:Certaines races, en particulier les grandes, sont plus sujettes au développement d'acrochordons.
- Friction:Les zones de la peau soumises à des frottements ou à des frictions fréquentes, comme sous le col ou autour des jambes, peuvent être plus susceptibles de développer des acrochordons.
Diagnostic des acrochordons chez le chien
Les acrochordons sont généralement inoffensifs, mais il est essentiel de les faire diagnostiquer correctement par un vétérinaire. Cela est particulièrement important car certaines affections cutanées, telles que les verrues ou les tumeurs, peuvent ressembler à des acrochordons. Un vétérinaire peut recommander un biopsie pour confirmer que la croissance est bénigne. Si votre chien développe une excroissance cutanée, il est courant que d'autres apparaissent au fil du temps.
Options de traitement pour les acrochordons chez les chiens
Bien que la plupart des acrochordons ne nécessitent pas d'être retirés, une intervention chirurgicale peut être envisagée si la tumeur devient irritée, infectée ou inesthétique. L'ablation se fait généralement à l'aide de méthodes telles que l'excision, l'ablation au laser ou la cryothérapie (congélation). Cependant, à moins que l'acrochordon ne provoque une gêne ou n'affecte la qualité de vie du chien, la chirurgie n'est souvent pas nécessaire.
Les acrochordons chez les chiens sont généralement inoffensifs, mais peuvent inquiéter les propriétaires d'animaux en raison de leur apparence. Un diagnostic approprié et une compréhension de leur nature bénigne peuvent atténuer les inquiétudes. Si un acrochordon devient problématique, consulter un vétérinaire sur les options de retrait peut aider à garder votre chien à l'aise et en bonne santé.

True cysts in dogs are fluid-filled sacs that develop under the skin and are usually benign. These cysts form when cells within the lining of the sac produce and secrete fluid, causing the lump to grow over time. While true cysts are generally harmless, they can become bothersome, depending on their size and location.
What Are True Cysts in Dogs?
True cysts are enclosed lumps that contain fluid secreted by the cells in their lining. Unlike some other types of cysts, which may be filled with semi-solid material, true cysts are filled primarily with fluid, making them soft and sometimes squishy to the touch. They can vary in size, from small, barely noticeable lumps to larger cysts that become more prominent over time.
These cysts can occur in any breed or age of dog, and while they are typically benign, they may need veterinary attention if they cause discomfort or begin to leak fluid.
Causes of True Cysts
True cysts in dogs are usually caused by a blockage in a gland or duct, leading to fluid accumulation. This blockage may occur due to:
- Trauma or irritation: Injury or repeated irritation to the skin can lead to cyst formation.
- Infections: Skin infections may block glands and ducts, contributing to cyst development.
- Genetics: Some breeds are more predisposed to developing cysts due to genetic factors.
Symptoms of True Cysts
True cysts are often easy to identify as they present as lumps beneath the skin. The most common symptoms include:
- Soft, fluid-filled lump: True cysts are typically soft or squishy, unlike tumors, which are usually firmer.
- Varying size: Cysts can grow over time, with some remaining small and others becoming larger and more noticeable.
- Fluid leakage: If punctured or damaged, a true cyst may leak fluid. This fluid can dry on the fur around the cyst, forming crusts.
- Discomfort: In some cases, the cyst may cause discomfort depending on its size and location. Cysts near joints or in areas where the dog is frequently touched may become bothersome.
Are True Cysts Harmful?
Most true cysts are not harmful to dogs. They are benign and generally do not pose any significant health risks. However, they can become problematic if they grow too large or are located in areas that cause discomfort to the dog. Additionally, if a cyst is punctured, it may become irritated or infected, leading to complications.
Treatment Options for True Cysts
In many cases, true cysts do not require any treatment and may be left alone unless they cause discomfort or complications. However, if a cyst becomes bothersome, there are several treatment options available:
- Drainage: A veterinarian may drain the cyst by puncturing it and removing the fluid. This is a simple procedure but may need to be repeated if the cyst refills.
- Retrait chirurgical: For larger cysts or cysts that continue to refill, surgical removal may be the best option. The entire cyst, including the lining, is removed to prevent recurrence.
- Antibiotics: If a cyst becomes infected, a veterinarian may prescribe antibiotics to reduce inflammation and prevent further complications.
Preventing Cyst Formation
While true cysts cannot always be prevented, regular grooming and skin care can help reduce the risk of irritation and blockages that lead to cyst formation. If your dog has a history of cysts, regular check-ups with the veterinarian can help monitor for any new growths and address them before they become problematic.
True cysts are common, fluid-filled lumps that can develop on dogs for various reasons, such as blocked glands or skin trauma. Although these cysts are generally harmless, they may cause discomfort if they grow large or leak fluid. If you notice a lump on your dog, it’s important to consult with your veterinarian to ensure proper diagnosis and treatment. In most cases, true cysts can be easily managed, allowing your dog to remain comfortable and healthy.

Les kystes chez les chiens sont fréquents et peuvent être causés par divers facteurs. Ces sacs remplis de liquide ou semi-solides peuvent apparaître sous la peau ou dans les organes internes. Bien que la plupart des kystes soient bénins et inoffensifs, il est important de comprendre ce qui les provoque et quand ils peuvent nécessiter une attention vétérinaire.
Causes courantes des kystes chez le chien
- Inflammation:L'une des principales causes de la formation de kystes est l'inflammation. Lorsque la peau d'un chien s'enflamme en raison d'une infection, d'une irritation ou d'une réaction allergique, les glandes ou les follicules pileux peuvent se bloquer, ce qui entraîne la formation de kystes.
- Trauma:Une blessure physique à la peau peut également déclencher des kystes. Si votre chien a été griffé, mordu ou blessé, le tissu endommagé peut se transformer en kyste dans le cadre du processus de guérison du corps.
- Follicules pileux et glandes cutanées obstrués:Comme chez les humains, les follicules pileux et les glandes sébacées (huileuses) des chiens peuvent se boucher. Lorsque ces voies sont bloquées, du liquide ou des matières peuvent s'accumuler, entraînant la formation d'un kyste. Cela est particulièrement fréquent chez les chiens à la peau grasse ou dans les zones où le toilettage peut irriter la peau.
- Toilettage excessif:Un toilettage excessif, que ce soit par léchage ou brossage, peut parfois irriter la peau et déclencher des kystes. Une irritation répétée peut provoquer un traumatisme mineur à la surface de la peau, entraînant le blocage des follicules ou des glandes, ce qui à son tour provoque le développement de kystes.
Races sujettes aux kystes
Les kystes peuvent se former chez les chiens de toute race ou de tout âge, mais certaines races ont une prédisposition génétique. Les chiens les plus susceptibles de développer des kystes sont les suivants :
- Cockers:Connus pour leur pelage épais et leur peau sensible, les Cockers Spaniels sont sujets aux kystes sébacés.
- Boxeurs:Cette race est prédisposée à développer diverses excroissances cutanées, y compris des kystes, surtout en vieillissant.
- Golden Retrievers:Leur double pelage épais et les problèmes de peau les rendent sensibles à la formation de kystes.
- Schnauzers:Les Schnauzers développent souvent des comédons, ou « bosses de Schnauzer », qui sont un type de kyste causé par des follicules pileux obstrués.
Types de kystes chez le chien
Les kystes peuvent varier en taille et en apparence, selon leur cause. Parmi les types courants, on trouve :
- Kystes sébacés:Ces problèmes sont causés par des glandes sébacées obstruées et sont remplies d'une substance cireuse. Ils sont fréquents chez de nombreuses races, en particulier celles à la peau grasse.
- Kystes folliculaires:Ces problèmes se forment lorsque les follicules pileux se bloquent, souvent en raison d'infections cutanées ou d'un toilettage excessif.
- Kystes dermoïdes:Ces anomalies sont congénitales et se produisent lorsque les couches cutanées ne se séparent pas correctement au cours du développement, ce qui entraîne la formation d'un kyste.
Traitement et prévention
La plupart des kystes chez les chiens sont bénins et ne nécessitent pas de traitement, à moins qu'ils ne s'infectent ou ne deviennent suffisamment gros pour provoquer une gêne. Dans les cas où un kyste devient douloureux ou gênant, un vétérinaire peut recommander de le drainer ou de le retirer chirurgicalement. Un toilettage régulier, la recherche de bosses et le maintien de la santé générale de la peau de votre chien peuvent aider à prévenir la formation de kystes. Si vous remarquez des bosses ou des bosses inhabituelles sur votre chien, il est toujours préférable de consulter votre vétérinaire pour un diagnostic approprié.
Les kystes canins peuvent se former pour diverses raisons, notamment une inflammation, un traumatisme, des glandes obstruées et un toilettage excessif. Bien que ces excroissances soient généralement inoffensives, certaines races sont plus sujettes à la formation de kystes en raison de facteurs génétiques. Comprendre les causes et savoir quand demander l'avis d'un vétérinaire garantit que votre chien reste en bonne santé et à l'aise.

As a pet parent, discovering a lump on your dog can be concerning. These lumps can be either cysts or tumors, both of which present similarly but differ significantly in terms of severity and treatment. Recognizing the differences between cysts and tumors in dogs is crucial for determining the best course of action and ensuring your dog’s health.
What Are Cysts in Dogs?
Cysts are enclosed pockets of tissue that form within the skin and are typically filled with fluid or solid material. They are often discovered by pet owners while petting or brushing their dog. Cysts generally develop slowly over time, and they are usually benign, meaning they are not cancerous.
Most cysts feel soft and are somewhat movable under the skin, although some can feel firmer depending on their size and contents. While cysts are non-threatening, they can occasionally become infected or grow large enough to cause discomfort, which may require veterinary intervention.
What Are Tumors in Dogs?
Tumors, on the other hand, are abnormal growths of cells that can be either benign or malignant (cancerous). Tumors can appear anywhere on a dog’s body and, unlike cysts, tend to feel more solid and are less movable beneath the skin. The growth rate of tumors varies; some tumors grow quickly, while others may take time to develop.
Malignant tumors are the ones that pose a greater risk to a dog’s health. They can spread to other parts of the body and damage vital organs, which is why early detection and treatment are essential. Even benign tumors, though not cancerous, can cause issues if they grow too large or press on nearby organs.
Key Differences Between Cysts and Tumors
While cysts and tumors may look similar because they both protrude from the skin, they have important differences:
- Consistency: Cysts are generally softer and filled with fluid or material, while tumors tend to be solid and less movable.
- Taux de croissance: Cysts develop slowly over time, while tumors can grow at varying rates, some very rapidly.
- Cause: Cysts are benign, while tumors can be either benign or malignant.
- Risk: Cysts are not life-threatening, but tumors, especially malignant ones, can spread and become dangerous.
Why an Accurate Diagnosis is Crucial
Although cysts are typically harmless, it’s still important to have any lump or growth on your dog evaluated by a veterinarian. A proper diagnosis ensures that you’re aware of whether the growth is benign or something more serious. Vets may use tools such as fine-needle aspiration, biopsy, or imaging tests like ultrasounds to determine the nature of the lump.
Understanding whether your dog has a cyst or a tumor will guide the treatment plan. Cysts may be drained or surgically removed if they cause discomfort, but tumors—especially malignant ones—often require more aggressive treatment, such as surgery, radiation, or chemotherapy.
Treatment Options for Cysts vs. Tumors
- Cysts: Treatment for cysts is typically less invasive. In many cases, they may not need any treatment unless they become infected or uncomfortable. In such cases, they can be drained or surgically removed.
- Tumors: For benign tumors, removal may be an option if the tumor is large or causing issues. Malignant tumors, however, require more extensive treatment to prevent them from spreading. This can include surgery, radiation therapy, or chemotherapy, depending on the type and stage of the cancer.
If you find a lump on your dog, it’s essential not to panic but to seek professional advice. While cysts are generally harmless and slow-growing, tumors can present a serious health risk, particularly if malignant. Consulting with your veterinarian for an accurate diagnosis is the best way to determine whether the lump is a cyst or a tumor, and to ensure your dog receives the appropriate treatment. Early detection and intervention are key to keeping your furry friend healthy and happy.

Inflammatory mammary carcinoma (IMC) in dogs is one of the most aggressive forms of mammary cancer. This condition typically presents as a rapidly progressing tumor that spreads extensively, making it difficult to treat effectively. Unlike other forms of mammary tumors, IMC tends to infiltrate surrounding tissues early on and spreads throughout the body even before a diagnosis is made. Due to its aggressive nature, the prognosis for dogs with inflammatory mammary carcinoma is often poor.
Why Surgery is Not an Effective Option for IMC
Surgery, which is often a first-line treatment for many types of cancer, tends to be less effective in dogs with inflammatory mammary carcinoma. One of the main reasons is the microscopic cancer cells that extend far beyond the palpable mass, making complete surgical removal nearly impossible. Even if the visible tumor is removed, there is a high likelihood that the cancer has already spread to other parts of the body, particularly through the lymphatic system.
In fact, studies have shown that surgery does not necessarily improve the survival rate in dogs with IMC. This is because, by the time the tumor is detected, it has often metastasized to vital organs such as the lungs, liver, and lymph nodes. As a result, the focus of treatment typically shifts to palliative care and managing the symptoms rather than attempting to cure the disease through surgery.
Current Treatment Options: Radiation Therapy and NSAIDs
Despite the limited success of surgical intervention, there are other treatments available that can help manage inflammatory mammary carcinoma in dogs. Radiation therapy has proven to be somewhat effective in slowing the progression of the disease. Radiation is aimed at reducing the size of the tumor and alleviating some of the associated pain and discomfort.
Another important part of managing IMC in dogs is the use of non-steroidal anti-inflammatory drugs (NSAIDs). These medications work to reduce inflammation and may help in controlling the spread of cancer cells. NSAIDs can be especially beneficial for improving the quality of life of dogs suffering from this aggressive cancer. However, it’s important to note that NSAIDs alone are not a cure, and they are usually part of a broader treatment plan involving other therapies.
Pronostic et qualité de vie
Even with aggressive treatments like radiation therapy and NSAIDs, the overall prognosis for dogs with inflammatory mammary carcinoma remains poor. Most dogs diagnosed with this condition have a life expectancy of just a few months to a year. The focus, therefore, tends to be on palliative care, improving the dog’s quality of life, and ensuring they remain as comfortable as possible during their remaining time.
Early detection is crucial for managing any form of cancer, but due to the fast-growing and highly aggressive nature of IMC, it is often diagnosed at an advanced stage. This makes it challenging to achieve long-term survival, even with aggressive treatment.
Inflammatory mammary carcinoma is a devastating diagnosis for dogs and their owners. Given the cancer’s aggressive spread and the poor prognosis, surgery is often not recommended as a treatment option. Instead, radiation therapy and NSAIDs are the current standards of care, focusing on symptom management and improving quality of life. While there is no cure for this form of cancer, these treatments can provide some relief for affected dogs and help them live more comfortably in their remaining months.

Pets often hide signs of internal health issues, including cancer, until the disease has progressed to a critical point. Many times, the first sign of an internal cancer may seem to appear suddenly, even though the disease has been quietly developing for months or even years. By the time a pet’s body can no longer compensate, the symptoms become noticeable, leaving owners surprised by the rapid change.
Understanding this delayed symptom onset is essential for pet owners, as it highlights the importance of routine checkups and early detection.
Why Cancer Symptoms May Appear Suddenly
Internal cancers can grow undetected for a long time because pets naturally mask their discomfort. In the wild, animals that show signs of illness or weakness become vulnerable, so they develop a strong instinct to hide pain. This survival mechanism remains in domesticated animals, often making it difficult for owners to detect early health problems.
While a cancerous tumor or internal issue may be silently developing, it might only reach a critical size or affect vital organs much later. Once the body can no longer manage, sudden symptoms appear, which can include:
- Lethargy and Weakness: A pet may suddenly seem extremely tired or weak, showing difficulty in standing, walking, or engaging in normal activities.
- Loss of Appetite and Weight Loss: Even though the underlying disease has been progressing for some time, a sudden drop in appetite or unexplained weight loss may be the first visible sign.
- Difficulty Breathing or Coughing: In cases where cancer affects the lungs or chest, pets may show sudden signs of labored breathing or start coughing unexpectedly.
- Digestive Upset: Vomiting, diarrhea, or abdominal bloating may appear without warning, even if the cancer has been slowly affecting the digestive system for months.
- Lumps or Swelling: While internal cancers often go unnoticed, a lump or swelling may suddenly become visible, indicating a more advanced stage of the disease.
- Sudden Collapse or Fever: In severe cases, pets may collapse due to internal bleeding or infection caused by cancer. Recurring fevers without an obvious cause could also be a sign of an underlying issue.
L’importance des contrôles vétérinaires réguliers
Because pets often hide signs of cancer until the disease has reached a critical point, regular veterinary checkups are key to early detection. Routine visits to the vet can catch subtle changes in your pet’s health that may not be obvious at home. Here’s why these checkups are so important:
- Physical Exams: A thorough physical examination can help detect lumps, swelling, or other abnormalities that might indicate internal cancer. Vets are trained to notice small changes that could be easily missed by pet owners.
- Blood Tests: While most cancers do not show specific markers in routine blood work, blood tests can still reveal abnormalities in organ function or blood cell counts, leading to further investigation.
- Tests d'imagerie: X-rays, ultrasounds, or CT scans allow vets to see inside the body and identify tumors or abnormal growths. These tests can detect issues long before they cause visible symptoms.
- Early Intervention: Detecting cancer in its early stages gives pet owners more treatment options and a better chance of improving their pet’s quality of life. In many cases, early intervention can slow or stop the progression of the disease.
What To Do If Symptoms Appear Suddenly
If you notice a sudden change in your pet’s health, it’s essential to seek veterinary attention immediately. Even if the signs seem minor, such as a decrease in appetite or a temporary period of lethargy, they could be early indicators of a serious underlying issue like cancer.
Some of the signs to look for include:
- Sudden weakness or inability to move
- Persistent coughing, panting, or breathing difficulties
- Vomiting or diarrhea that lasts for more than a day
- Abdominal bloating or visible swelling
- Perte de poids ou perte d’appétit inexpliquée
- Recurring fevers without an obvious infection
By catching these signs early and taking action, you can give your pet the best possible chance for diagnosis and treatment.
Cancer in pets can develop quietly for months or even years before symptoms appear. When signs do emerge, they often seem sudden and severe because the disease has reached a point where the body can no longer compensate. This makes regular veterinary checkups essential for early detection. By monitoring your pet’s health and acting quickly when changes arise, you can help detect cancer early, giving your pet the best chance for effective treatment.
