Karlotta absolutely LOVES this ball! She has no interest in any other plastic toy (she's a snob for lambswool & squeaky toys), but she lights up when she sees this ball. I've tried several treats, but Pedigree Marrow Bones seem like they were made for this. The one drawback is what a mess all the little broken pieces of treats make when they're being worked out of the ball, but that's a small price to pay for all the enjoyment it brings. My Mom fills hers w/ canned food each morning, freezes them during the day, & gives them to her dogs at night. To clean: I just soak in water & scrub what I can. I highly recommend this toy.

Pros: Endless hours of fun

Cons: Cleaning up pieces of dog treats

A few times a month I'm gone from home all day. I love having a toy that keeps the dogs amused for hours and keeps them out of trouble. It's so much fun for them to be able to get their own treats. They never get tired of it and it keeps me amused too - finding different things to put in it.

Pros: Very durable and fun

Cons: Haven't found any yet

My dog loved this. However they tear up easily and do not last long. Therefore you end up watching the pet so they do not choke on the plastic or rubber. Some smaller dogs may do better but my border collie destroyed this in 45min or less!

Pros: fun to play with

Cons: tear up easily

When I saw how much fun my dogs had with their Kong, I got one of these to fill for the other dog. I like to stuff it with treats and then kind of seal the hole with peanut butter. It keeps them busy and out of trouble for hours.

Pros: Good for destructive dogs, durable, fill with goodies

Cons: None

I bought one of these for my father's poodle, and he absolutely goes crazy for it. He's been chasing it around the house for days.

Pros: fun

Cons: none
