Stewie has been chewing at his armpits lately & I have no idea why! He's never done this before. He doesn't seem to be itchy anywhere else. I've switched his food recently (Hills k/d to Solid Gold), but that was after he started this. I gave him heartworm med at the beginning of the month, but it's never bothered him before. I was giving him canned food with his dry for a little while (both were the k/d). He's due for shots (just since the beginning of the month though) I'm going to try taking him in to the vets next week for a couple of shots & I'll have them look at it then, but I was just wondering if anyone had any thoughts in the meantime.
Here's a couple of pics him if that helps!
And this is the other one...there's a couple of little bumps on this one.
