Dogs love it and so do I
Size: Small
I have small dogs (<20 lbs) and they would chew on these forever if I let them. Never had any pieces break off. While this isn't the hardest toy to clean, it isn't the easiest either. Very worth the money and so much easier to use and safer for them. There's no danger of them breaking or swallowing part of the brush which has happened in the past. I highly recommend this dental toy, especially if your dog tries to chew on the toothbrush when you brush their teeth.

Good Idea, didn't Match Expectations.
Size: Large
Heavy and a bit difficult to 'load.' Maybe too hard for our dog. He did carry it around but didn't try to get treats as well as expected and it's quite difficult to clean. Maybe best for a larger more aggressive dog than a 65 lb. lab mix.

This Bites

We've happily used OxyFresh pet water additive for probably around 15 years. I love that product, so I figured their toys would be great too. Not so much. The concept seems good. This does feel like a heavy duty rubber and it feels like a sturdy construction, but in actuality, it did not hold up. Without a goal like food in it, my two dogs had 0 interest in this. It says you can put a treat in it. I wrestled to put a piece of kibble in the jaws of this toy, but that was tough and there isn't much room in there. That did pique their interest. Both my boys are about 50 lbs. One is a heavy chewer and the other is pretty gentle mouthed with toys. BOTH dogs were taking chunks out of this immediately. I must say that I'm really disappointed. If the rubber held up, this is a fantastic concept and seemed like it would work very well to clean teeth. Unfortunately for us, this was an expensive toy that began to fail within about 15 minutes of what seemed to be very average use. We'll be continuing to use a toothbrush instead.

This is a great toy! I have a heavy chewer that destroys other toys in seconds. I have had this for 6 months and it still looks new.
