My dog was attacked by a dog two days ago. One of his injuries is a hole under his front arm. When I took him to vet not long after, I boticed a lump around the hole. Is this just swelling or infection?

It could be swelling from the bite, but there is a chance it could be due to infection. Without seeing him in person, I can't say for certain, but have a vet check it out if they have not already. Best of luck.
