My dog has a strange ball-like lump on his tail. Is it dangerous?

I recommend to have Leia examined by the 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 examine under the microscope to determine what this is and if further treatment is needed. Have this checked out soon.

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

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.

The bump could be caused by an infection, allergic reaction, cyst, benign or cancerous mass. The only way to know for sure is to have your vet do a fine needle aspirate. It is a very easy proceedure that takes just a few minutes. Once it is diagnose, your vet can decide the best treatment. Please call your vet and schedule an appointment, especially since it seems to be bothering her.

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. 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. Once the cause of the lump is diagnosed, the vet can discuss treatment options with you. I'd give his vet a call today to make him an appointment. Best of luck.

Hello. From the photo that you provided, this looks like a growth that may be benign or malignant. It may also be a cyst. Your veterinarian can try to do a fine needle aspirate on the lump in order to determine if it is urgent to surgically remove it. As to whether the hot spot caused it…. that is not likely. Your pet may be licking or chewing at it and it may have had some part in causing the hotspot, but I cannot say for sure. Your next step should be trying to determine if surgery is needed to remove it. Your veterinarian can help you with that. Thank you.

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.
