Not sturdy toy
Toy was not as big as we thought it would be and in addition the dog ripped it up within 2 weeks. Expensive for not lasting very long.

Not for heavy chewers.
Does not hold up to our german shepherd. If you have a large dog be aware the seams will separate. But this is our dogs favorite toy. We gad to buy two within 6 months.

Not for playing tug!!
Great toy, but we played tug with it and one of his flippers came off. It is great when my MBT just shakes it! Don’t recommend playing tug!

Instantly Loved by my Mini Aussie!
I wondered how long before my sharp-toothed mini-Aussie completely destroyed this cute duck toy. It was a Christmas present that he loved instantly. He plays with it everyday and it hasn't shown any tears or loose threads as he has destroyed other supposedly "tough" toys. Was happy the "quack" is audible but not annoying. Perfect. In a short time it became his favorite toy.

Cute fun toy
Style: Squirrel, Style: Squirrel
My pup doesn’t play with toys, she’s food driven but she absolutely loves this. The plush squirrels are just toys, but she goes after them like they’re treats. She chews and tosses them around once she gets one out. They haven’t torn, and it’s been a week so far. The quality of the tree and plush toys are higher than other burrow toys she has. It comes with 4 which is better than the typical 3. She’s small and though it doesn’t seem to be more difficult because the toys are bigger, she’s satisfied after getting only 2 out. Worth the little extra money.
