I was rubbing on my dog tonight found that there are two knots right behind each of his legs in the same spot don't feel hard they just feel like fat I believe? Are they any signs that I should be worried

Depending on where the "knots" are, it is possible it is normal anatomy, however there could be something else going on. You may be feeling Cruz's lymph nodes if the "knots" you are feeling are behind the knees. Normally lymph nodes are small and not readily felt by owners, so it is very possible if you are able to feel them easily, that he needs to be checked out. Enlarged lymph nodes can be a nonspecific sign of infection or inflammation and should be checked out by your vet. Cruz is very young and so fatty lumps like lipomas, which are benign fatty tumors, are less likely. I would recommend having him checked out by your vet to see if these areas need to be investigated further or not.
