I got this for my 22 lb shih tzu who is pretty good at figuring things out. He is totally disinterested in this toy (which I bought at retail for $20). He doesn't find the treat at all appealing and because the flaps seem rather stiff, his kibble doesn't come out. He has a cube that I fill with kibble that he rolls all over the house and he just loves that--but this doesn't do it for him.
$20 would have paid for a lot of treats!!

I noticed some people were saying that their dogs were getting the treat out in 10 min. Make sure you put one of the hard treats in both sides of the treat ball, this makes it harder for the dog to manipulate the ball to get the treat out.

The everlasting treat ball lasted about 5 minutes for my Scottish terrier mix. Luckily the store is willing to take a return as it cost $18.99 for something that didn't last as long as a $1 pig ear. If your dog is at all a powerful chewer don't but this toy as it won't last.

I did think this was a little pricey for a dog toy that might be destroyed within minutes, but I took a chance anyway. I am glad I did...my dog loves this thing. He was able to get the caps that came with it out quickly, but when I bought replacements they looked to be a little different texture and he has not popped these out yet. He also loves it when I put treats inside for him to chew out which I do without using the caps.

I did have an issue after about a month when I purchased the new caps. Since he was not able to pop the caps out (which he shouldn't be able to do), he was chewing constantly and did cause a couple of scissor like cuts in the rubber with his teeth. It's not bad, but it could result in rubber chunks coming off. I wasn't sure if anything could be done, but I contacted the customer service of the company that makes this and they were extremely helpful. They replied to my email same day (that never happens!) and they did say that they have had a few cases where this has occured in the rounded edge of the ball. They also said they were sending me their everlasting fun ball free of charge as that type of toy might work better. Wow! That's customer service.

All three of my dogs love this toy. I have used other treat toys (i.e. Kong, tricky treat ball, buster food cube, canine genius) but this is their favorite and last the longest. My Mini Aussie is a tough chewer and she has not been able to destroy this. (Wish I could say the same for our furniture, base boards and several toys!) I put disks in both side and fill the middle with kibble or other treats. It takes them a couple of days until all the treats are gone. Great for when we have guests or want to sit down and watch a movie. I love it, love it, love it!!! It is important to get the right size. I use the small on my 8lb dog and the medium on my 14 lb terrier and 17 lb mini aussie. I agree it is not the best for crate training, for that I would stick to the Kong because you don't need space to roll it around to get the treats out. But for everything else, this is the best treat toy!
