Last night my husband noticed a lump on Sam's neck. It's really obvious so I can't imagine it's been there for long. He doesn't seem at all bothered by it. He yelps and squeals a lot, but that is just how Sam is, it's nothing new and doesn't seem to be associated with touching that area. Does anyone have any ideas what this could be? I'm attaching two photos that show the swelling.
It will be pretty difficult for us to get him to the vet right now because of the holiday and then I'm being induced for my baby on Wednesday first thing in the morning, I have no idea if they'll be able to get him in on Tuesday.
