The belly pouch is pretty normal Bob has it and RB Flicka did. Joey is the exception. If it is there it does not show at all. Bob's does not exactly disappear when he lays down.

I think that going to the vet is a great idea if you have any quesiton as to what it is. If nothing else you will have peace of mind. That is worth alot.

Let us know what the vet says.
