Sadie Mae Approves
Our Pittie mix absolutely loves these balls! She chews them and we play catch for hours and they haven't shown any signs of damage after several months of play. I highly recommend!

Enrichment toy is working
We have had these for a while. Got them for enrichment during the AZ summers when it is too hot to get outside. They are very durable. We do have to use cheese spray to fill them.

Not meant for small dogs.
I bought this toy ball hoping it would be a fun treat dispenser for my Shih Tzu, but it’s way too big for her to handle. The grooves are really deep, so treats just get stuck inside and she can’t get them out. The texture is also super slippery, so she has trouble keeping a grip on it, and the plastic is heavy and not flexible at all. Overall, not a great fit for small dogs.

It'll only last a week
Size: 5 Inch, Color: Classic Bone, Size: 5 Inch, Color: Classic Bone
We've only had it a few days and she's already half way through it. It won't last the week. She doesn't eat it, she spits out the pieces. If you buy it was a consumable, totally worth the money. I'll probably buy my power chewer a couple a month
