What’s this bump on my dog’s chest? It’s slightly raised and roughly the size of your pinky fingernail. It wasn’t there one day and then it was there the next. It has been roughly 36 hours since I found it and it has not grown or shrunk. It does not seem to bother him at all like you would think a bite of some sort would. He’s not licking it at all and does not care when I mess with it.
