My dog has a pea-sized lump on his leg he keeps licking. What is it?

Question

This is on my 16 month old Golden Retrievers back right leg, how concerned should I be as the nearest bet is 2 hours away? Is it an ingrown hair or a bite of some sort or something else? It is about the size of a large pea. It doesn't seem to be bothering him to much, tho he does lick at it. Pet's info: Dog | Golden Retriever | Male | unneutered | 1 year and 4 months old | 75 lbs

Thank you for submitting the pictures of Chewie's leg. It appears like he has a mass growing on it. I do recommend he sees his veterinarian to have it evaluated. Typically a procedure known as a fine needle aspirate is performed. Cells are collected and the veterinarian looks at them under the microscope. The goal is to determine if the mass is potentially cancerous or not. There are two common skin masses that can look like Chewie's. One is a cancerous mass known as a mast cell tumor. This can be an aggressive form of skin cancer and would need to be surgically removed. The other is a benign skin growth known as a histiocytoma. This mass doesn't usually cause problems and can regress on its own over 2-3 months. I hope this helps!
