No. Just no.
Size: Critter Zoo, Color: 5 Different Animals, Size: Critter Zoo, Color: 5 Different Animals
From the Amazon listing, Nocciola promises “Durability Guaranteed” and “Expert Craftsmanship,” boasting multi‑layer composite fabric, chew‑resistant construction, and meticulous stitching.
Yeah… about that.
Within the first ten minutes, the giraffe’s squeaker gave up the ghost. By the thirty‑minute mark, one of our puppies had already liberated one of its appendages and was preparing to eat it. When I took the giraffe away, he immediately redirected his enthusiasm toward the mallard and removed a wing.
Our other puppy went straight for the Red‑Headed Chicken’s throat. She succeeded. She was also making impressive progress on opening the back of its neck.
At that point, all three toys had to be confiscated, and the remaining two are still sitting in the box untouched because I value my dogs’ digestive tracts.
To be fair, the toys sound fantastic—literally. My puppies adored the squeaks, honks, and crinkles. They had a blast tossing them around and sprinting through the house. But the moment they settled down for a chew session, it was game over.
I’m genuinely disappointed that these toys require constant supervision to prevent accidental ingestion, and that my dogs can’t safely enjoy them the way they’re meant to.
If your dogs chew even a little, these toys are not worth the investment.

Dog Toy
Size: Critter Zoo, Color: 5 Different Animals
These things were good for the first 45 minutes than my dog ripped it apart. Buy the variety pack it helps to keep the dog happy.

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.
