Dog likes it, but is very hard material around smaller dogs when he is playing and running
Color: Blue
My 22lb dog loves this chew. We have owned it just for one day. He immediately loved it and he races through the house holding it in his mouth like a grand prize.
I have concerns to the hardness of the ends of it, the material is very hard, and the tail comes to an end shape that could hurt other pets in a multidog home if it hit or stuck in them. I have two smaller chihuahua dogs, one who has lost an eye so this is something to be careful about with other dogs running with this toy. This may not affect a one dog home. Best to observe the dog while playing with it around others.

Strong and holds up to aggressive chewing
Color: Blue, Color: Blue
This was a fast favorite for our extremely aggressive chewer ('indestructible' toys are typically destroyed within hours)... this has survived about a week and still going strong.

My dog is a very aggressive chewer.
Color: Blue
My dog is an aggressive chewer and this lasted about 3 weeks before he started to get into the plastic and I had to throw away. It lasted longer than other chew toys so it was good. However the tail makes it easier for him to chew off into pieces. He gets nervous and needs to chew on something. I find the hard cheese sticks a better option for his nervousness.

Thinks a fun little sniffy toy
Color: blue, Color: blue
My puppy seemed curious and didn’t mind playing with this sniffy toy. It’s large and well made and has plenty of title spots to hide stuff. I put kibble in it and my little puppy sniffed and googled a way. I guess this is great for keeping dogs busy and entertained. It’s a pretty cool little way to give dogs treats or snacks.

Durable
Color: Multicolor A, Size: 2.5"(Medium)-12 Pack
Our dogs love these balls. They seem to be sturdy for our strong jawed dogs and they love the squeaker. We haven't had to replace the first two balls we e had out playing with yet.
