No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long.
I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Great toy/feeder
My dog loves this!! It gives her entertainment and I use it for some of her breakfast. I put some in this and the rest in her usual food bowl. She goes to this first for the fun then goes and eats the rest of her breakfast from the usual bowl. Also good for slowing down eating while they have fun!

Good puzzle
My dog used to get puzzles often and loved them. We lost a lot of them in a house fire and subsequently move about a year ago and Im finally starting to replacing her old ones.
She loves this thing. She definitely needs supervision because she’s already scratched it a bit from biting on it too hard but reasonably durable with that aside. (My dog is tough chew toys only kind of dog so fully expected)
Easy to set up and fun for her is all I needed and it hit the mark

A fun puzzle for cats!
My 5 month kitten took to this puzzle right away as he watched me put food into each compartment. He solved it quickly and I think it will be a fun resource for his cognitive growth on a daily basis.

Great for mental stimulation.
Great for mental stimulation. Our little guy figures them out pretty quickly. He is very treat motivated. This one is excellent as sn activity to slow him down from gobbling his treats up so quickly.
