Uhoh, I have self-diagnosed Sammy, who is ten weeks old, with an umbilical hernia. I was playing with his feet while he rested, and noticed a little lump on his belly- not even as big in diameter as a dime, and soft, under the skin. It's not discolored or anything, and a little research has me thinking it's a hernia. As far as I know, this is its first appearance, but I'm reading that can happen as the pup gains weight.
So, do you think I'm right? I put him on his back and massaged the bump some, and it mostly went away- I think whatever fluid had gotten out went back in. But should I have it repaired at this point, or wait to see what happens? The vet didn't notice this when we were in before, and I think it's a new development. It's definitely a soft bump, not hard or scar tissue-y at all, so does that mean it needs to be fixed before it gets worse?
Thanks!
