Doggo Fun
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
My dogs like these they were just smaller then I thought. They are made for medium dogs. Our big doggo can put the whole thing in her mouth. The squeek isn't too annoying and the overall make of the toy is nice. If you have a doggo that likes to attack and get the squeeker out this toy isn't a match for them. They will distroy it in minutes. If you have a dog that loves to just carry stuffies then these are good for them.

Very durable and fun to play with
Set name: Stuffed Animal Dog Toy Set (5 Pcs)
I've had them a few weeks now and my dog that destroys other chew toys hasn't made a dent. My smaller dog made 1 his favorite and sleeps with it. Overall, I think it's a good deal.
