My dog has a growth on his paw. He's licking and limping. What is it?
Hello, thank you for using PetCoach.
This looks to be a histiocytoma tumor which is a benign tumor commonly found on the limbs and face of dogs. It is a benign tumor that usually will regress on its own within a few weeks/months with no treatment. Of course, I am just guessing. It is impossible to diagnose these things via the internet with just a photo. Here is an information sheet about histiocytomas in dogs for you to read.

He should not be licking the tumor - if he is, you need to get him a cone collar to wear to stop that behavior. If he is just licking the paw, that is not likely related to the tumor and is a different issue.
As always, if you are worried, you should take him to your vet for an exam.
Best wishes.
