Durability sucks dont buy
I purchased the Mellow Duck dog toy specifically for its supposedly durable construction, hoping it would provide at least a few weeks of entertainment. Unfortunately, the toy was completely shredded and destroyed within 24 hours of its arrival.
For a product marketed as suitable for dogs, the material quality is extremely poor and clearly not designed to withstand even moderate chewing or play. This was a significant disappointment and a total waste of money. I cannot recommend this toy for any dog, as it offers zero long-term value.

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.
