We havea a cute little Chhuahua than absolutely loves to chew on plastic toys. Legos, Bionicles, Toy Soldiers, he has destroyed them all. One good thing is that this is teaching the kids to pick up their toys off of the floor.
We have bought Biscuit tons of chew toys but they don't really catch his interest enough.
Well, I have found a chewy bone that has a built in replaceable chewy treat, that the dog just loves. It's called a Gnawhide, and you can buy refills of the little discs so they dog gets a treat while he chews on the bone. Love it!
