Longer Lasting than most things I've tried
Size: 1 Count (Pack of 16)
I bought these to go on the PetSafe Bouncy Bone which I had bought for my Australian Shepherd/Vizsla mix puppy who chews everything. We had gone through so many "long-lasting" chew toys/bones that really lasted only about 10 minutes and I was looking for something to occupy his time a little longer. These do the trick. Although they still don't last super long, they take a little more effort and keep him distracted a bit longer than anything else edible that I've tried. To me they are a bit pricey, so I try to make them last by only putting one on at a time, instead of one on each end of the toy. I also tighten the ends pretty tight to make it more difficult for him to get at the entire ring. If you don't mind the price, these are an easy and convenient way to keep your dog busy.

PetSafe Busy Buddy Refill Ring Dog Treats
Size: 1 Count (Pack of 16)
Great! My Baby Pearl Anne loves them. And, she won't normally play with anything else. The Vet says it's due her being in a HORRIBLE Puppy Mill. She never had a puppyhood. She is still Neurotic, even after having been her parent for over 4 years. I would definitely like to get my hands on these people, if I knew who they were. She was found her on a VERY busy intersection way up north in the Texas town where I live.
I don't normally go in this neighborhood, so I didn't see her on the street. My best friend, who died just 4 years ago on the 18th of March, had a ex coworker. Leslie(my best friend),KNEW I wanted a dog. I fell in love with her dog: a Miniature Schnauzer. One day Leslie's coworker called her. She said they had found a dog on the street. The coworker said that she couldn't keep anymore dogs. She has 3. So, when they described her, I knew I wanted her! She's a rare pure white Miniature Schnauzer. She was skinny, shaking, with horribly matted hair. She was scared to death, and freezing to death. I put her in a towel, and took her the Vet. And, she said she had worms, was dehydrated, and malnourished. not anymore. She's my baby, my child. Who is now spoiled to death.
Sorry this is so long, but, I really needed to tell her story.
Donna Valentine-Jones.
