I didn't read everyone's posts, but just wanted to share the danger of having a dew claw...if you're like Momo. He had his torn off while playing w/his fav ball. He likes to roll his ball under the couch & bat it w/his paws back & forth. Our old couch @ the time had a sofa bed, so there was room for him to play w/his ball w/out it disappearing under the couch. I think this is how he hurt himself...maybe it got caught on the fabric or something, although I never found his nail.
One night, he kept licking his paw, darting back & forth, licking, darting back & forth & so on. It was weird, so I picked him up thinking he had something stuck on his paw & to my horror, his paw was bleeding!
His dew claw was totally ripped out. I put clotisol on it & he screamed.
He was bleeding so much that the bandage I put on him was seeping w/blood. Took him to the vet & they cleaned it & bandaged it up real good. His nail grew back fine.
We threw away that old ugly couch when we moved loll. He now purposely drops the ball from the leather couch & barks to tell me to pick it up for him.
He likes playing w/me too.
