My dog has a visible, walnut-sized lump on his tail. What to do?

This lump on Alfie could be a cyst, an abscess, a benign tumor, or a malignant tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Alfie seen by a vet tomorrow to have this lump examined and diagnosed so it can be treated as needed.

I can't tell for sure from the photos but that looks like it may be a skin tumor. I recommend to have Goofy examined by his veterinarian. Skin masses can be many things but red raised masses are especially concerning for a skin cancer called a Mast Cell tumor. Your veterinarian will need to collect a sample of cell to examined under the microscope to determine what this is and if further treatment is needed. Have this checked out soon.

Thank you for submitting your question regarding Otis Lee. He will need to see his veterinarian for a procedure known as a fine needle aspirate. The veterinarian will use a small needle to collect a sample of cells to evaluate under the microscope. This will ideally give you a diagnosis for the bump. A histiocytoma is common on the extremities of a young dog. This is a spontaneous growth usually goes away on its own. However, a cancerous mass known as a mast cell tumor has the same outward appearance. In the meantime, place an E-collar on him to prevent any further self-trauma. I hope this information helps!

Give Rosemary's vet a call to make her an appointment.

This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Hercules to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

Hi Michael! This looks like a growth on Diego's tail, and it could be benign or malignant. Any suspicious lumps should be examined by the vet.

Yes, I would be concerned this may be serious, especially if it has grown quickly. The broken surface is very high risk for infection and I recommend an urgent assessment by your vet; biopsy and possible tail amputation may be required. In some male dogs, a hormone dependent condition can cause similar masses and castration can be helpful in these situations
