Yes, it is hard to tell from a photo. I agree, it would be best to have your vet look at it. It's hard to get appointments some places these days, but I hope you have a good enough history with your vet that Cody will be seen!
I'm sorry to hear about Cody having yet another problem, but you're a great owner for seeing that he gets prompt care for his problems. {{{{{Dee and Cody}}}}}
