I have a 5 month old puppy who constantly wants something to carry in his mouth and something to chew on. This treat dispensing toy has entertained him more than any others and has held up to sharp teeth, strong jowls, pawing, and lots of slobber. Nice to be able to rinse it off and it be ready to go again. As for dispensing treats- If you add several pieces of kibble those pieces will fly out with one of two bounces. Personally, I was hoping the treats would come out more slowly and not fly everywhere. Peanut butter is a messier alternative, but best avoided. That being said this product has held up longer than any other toy we've tried. The squeaker isn't too annoying, (my puppy is actually baffled by the sound), but it doesn't stop him from enjoying the toy.My dog loves it but it's a little small for a big dog. Also I couldn't find any treats specifically to fit this ball.My chew aggressive dog figured this out quickly and is able to get all the treats very quickly. It keeps his attention well while there are treats but doesn’t long.Excellent and very tough. It does have a little squeaker inside but it takes a really really strong jaw to make it go off.It's interactive so that she has something to keep her entertained during the day.Bought this chew toy 5 months ago. Now, that may not seem like a long time to say something is durable, but I have a Lab and a Rottweiler. Both less than 2 years old. They love to chew! And this is the favorite toy for both of them. Lots of chewing going on. It is nearing the end of its useful life as bits of it are being chewed off. However, it has made it for 5 months! And still squeaks! Usually the squeaker is the first to go, but the pups haven't been able to chew it apart to get to the squeaker. When my daughters dogs (Chow mix, Catahoula mix and Rottweiler) come over, this is the first toy they run to. My son's dog (Malinois mix) comes over, he too grabs this toy first. So, it has seen some chew time. Definitely will buy again.This toy has been long lasting. My chew crazy dog is not damaged it!Our 2-year-old lab mix is very good at shredding so-called "tough" toys, yet we've had this one for more than a week and it's still all in one piece - impressive! Both the 2-year old and the 13-year-old dog enjoy this toy. The noise it makes is gentle on the nerves., Excellent design!They arrived the next day! My dogs love them! Heavy chewers at 150 and 110 lbs. I put peanut butter in the crevices and it kept them busy for a long time! No damage to them at all after a few days of vigorous chewing!
