Hannah--this is she in my profile pic--is eleven, she paralyzed at age five. I lost one of her sissy's in Oct of 2010 and, shortly after, Hannah started obsessively licking her bowl after a meal. Now, she's licking our elbows in bed! She stops the second I ask her to, but I am concerned that she may either be still grieving Shari, or else still a little overwhelmed by our new puppy Shana. I've talked to the vet about it and he says that older dogs often do this--he thoroughly checked her out and, there is no return of her cancer and she is, apart from paralyzed, very healthy. Hannah seems as content and happy as ever, so I may be worrying over nothing, but I want her to have the best life possible. She has a wheelchair, she takes vacations with us, and she is nothing less than perfect. Should I just stop worrying about it??
