Isis is darling! By all means do a 'well baby' visit with your vet, and order the DNA swab for fanconi, huge peace of mind. I had a wonderful Isis many years ago, I love the name!
My dogs do this all the time. Well, Lexi does anyway- she's the only one who can fit/balance on the back of the sofa. ;) ha! And she'll tap your head in a heartbeat if there's something you have that she wants! lol
