Hi Olga
Well, in my practice I have come across a lot of these kind of cases. I think this is just a lump or skin mass. Skin masses are very common in dogs. They can be found on the skin (cutaneous tumours) or under the skin (subcutaneous tumours). In the majority of cases they are benign lumps caused by a fatty mass under the skin (lipomas), a blocked hair follicle (sebaceous cyst) or an enlarged oil gland in the skin (sebaceous adenomas). A lump or growth can, however, be a malignant tumour requiring immediate treatment. It is, therefore, essential to get any suspicious changes in the skin checked out so that your vet can assess whether the mass is benign, needs to be removed or is a danger to your dog’s health.
the two most common lumps in dogs are lipomas and sebaceous cysts. “Lipomas are fatty lumps under the skin, especially around the rib cage, common in middle-aged dogs. They are more common in overweight dogs but can occur in any dog. They are really like abnormal fatty tissue, although technically they are a benign tumour.
Cancerous lumps are diagnosed most often by needle aspirate or surgical biopsy. “A needle aspirate is quick and painless (usually) and is generally sufficient to determine if a lump is cancerous or not. A more precise diagnosis may need a biopsy,
Well I would recommend you to not to panic. Visit a vet clinic when you feel it is necessary.
Thank you
