Yeah I just got some toothpaste from our vet...Beckham thinks it's a treat and tries to eat my finger while I'm brushing his teeth. He loves it, I've also heard that dogs/puppies love the vanilla mint flavored pet toothpaste? Never tried it myself.
When I'm brushing my teeth before bed (while sitting on my bed) Beckham pops a squat right in front of me, looks at me with his big brown eyes and then will 'shake' my forearm until i rub some toothpaste on his nose. He loves it and always tries to get some from me. I never give him more than a tiny itty bitty streak on his nose and so far no issues, but I guess I better stop if it could make him sick.
