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
I think I saw Sophie on a b video website and I was so glad that someone else's B made that noise I showed it to my husband and daughter. Thanks for posting that video because as a new B owner we thought we had some kind of devel dog!!! She does it the most to our oldest dog Josie. There are nights she even does it from under our covers in bed when she hears Josie moving out in the living room. Too Funny!!!!
