Is it possible my havanese ate a whole bully stick in 1 hr?

My very old 12 lb poodle, with few teeth, can go through a 6 in. bully stick in 2 days.
So, it does not seem unlikely that a young dog with a full set of teeth can make one disappear in no time at all.
They love those smelly things. A friends pit mix devours a large one...maybe 18" in about 30 minutes.
If you don't think your dog is capable of that, check his favorite hiding places, like in between the sofa cushions....how do you think I know that little secret?

I highly recommend getting a real, uncooked beef or lamb bone from either the farmers market or a butcher- it takes the monster a good while to become bored of it (probably 3 days before all the nasty meat is gone, eventually I throw the bone parts away after a week or so.) Be warned, though- they make Bruno's beard-fur and hand-fur (where he holds it) smell freaking disgusting. Really, really gross. And, if he's like mine, he'll want to bring it directly up on to the couch which is sort of disgusting... however, I think its better for them, is cheaper and lasts longer. Just be prepared to bathe him!
