This might work on some of the outside things (plants and such)...we used a mix of hot pepper juice (habanero, tabasco and any other pepper I could get my hands on!). Roxey wanted to chew on all the vegetation outside and this worked pretty well, of course till it rained then we had to reapply

I've said this before and I'll say it again, I think the best bones for puppies are the Steralized Bones. I swear by those things!

Have fun with your chewing puppy
