My dog has a lump near his Achilles. Will it go away or grow?

Yes, typically lumps can be removed. Given that it has gotten bigger on Casino, it would be best to have the lump diagnosed and removed. It could be a cyst, a benign tumor, or a malignant tumor. I would take Casino into he vet tomorrow if possible.

Looking at the photo and considering your description of the progression of this, I would suspect that it is a growing mass. It could simply be a fatty lump such as a lipoma. Other possibilities would be a soft tissue swelling due to trauma, but this seems less likely considering the progression. I would head to the vet and get them to test the lump to see exactly what it is. If it is just a lipoma and not causing bother it should not need to be removed.

Thank you for providing pictures of Gucci's bump. From the pictures, it looks like it could be a cyst, 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. Once the cause of the lump is diagnosed, the vet can discuss treatment options with you. Given that the lump is getting bigger, I would have him seen by a vet on Monday. Good luck, I hope this helps!

That lump is quite big, and given that it's gotten bigger quickly in a short period of time, it is a worry. I would take Mixie back into the vet to have this checked out. It may need to be removed. Best of luck.

It is possible this could be a cyst. Cysts can decrease in size, especially if the vet used a needle to aspirate fluid from the cyst. They do not, however, usually go away completely and will often fill back up. In some cases, these cysts will rupture and can cause pain or result in infection, so the best course if it seems to be causing problems is to remove it surgically.

Poor guy. This is a skin mass and needs to be tested by your vet to determine what kind of tumor this is. If it seems to be growing uncontrollably then having it surgical removed should be considered. Inquire with your vet about if Rupert is a good surgical candidate and what it would entail getting this removed. Best of luck with Rupert moving forward. Best wishes and take care.

This could be a benign tumor, but it is concerning that it's gotten bigger. 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 its 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 if needed. I would give Tavia's vet a call in the morning to make her an appointment. Best of luck.
