Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

    I would not be too concerned with that bump on his head. Looks like it is a benign cyst. As long as he is not bothering it and it hasn't changed, it doesn't grow and become red or your irritating, I think you should be fine to just keep an eye on it. If it does change quickly then I would recommend taking him into your vet to have it checked out. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

    It's impossible to say exactly what a lump is without doing a bit more investigation. It could be something benign, such as a cyst or a wart. Or it could be a malignancy, as there are several common types of skin cancers in dogs. I would recommend getting Charlie into your vet, who can have a look at the mass and perform a test called a fine needle aspirate, if he/she feels that it's warranted. That way an exact diagnosis can be made and a treatment plan developed.

    This could be a cyst or a benign growth. 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. Give Sushi's vet a call to make her an appointment. I hope this helps!
