Great for Small to Medium Dogs
Size: Critter Zoo, Color: 5 Different Animals
I bought these for my boys to play with. One of them loves to tear the squeaker out of anything that, well, squeaks. These do more than squeak! So far, they have survived the terrorist chihuahua/piranha boy!
They’re pretty awesome toys and my kids’ favorites! They’re sturdy and goofy looking!
I’m writing this review a couple months after my purchase. One reason why is I want to “buy again” (just because they have their squeakers, doesn’t mean they haven’t been chewed on!).
I have a large, long chihuahua (<—— terrorist/piranha boy) and a min-pin mix. These toys are the perfect size for them. There is some chew damage from the terrorist but considering he can get a squeaker or of a Lamb Chop within 5 minutes, I’d say these toys are the best I’ve run across in quality, thickness of the material, minimal stuffing and durability.
Highly, strongly, encourage you to, purchase if you’re looking for good toys for small to medium dogs!

Great variety for a good price!
Size: Critter Zoo, Color: 5 Different Animals
We have a grand puppy that is full of energy, and loves her toys! The squeakier the better! We ordered these, and we enjoy introducing a new toy each time they come over. Good quality, strong squeakers, and a happy puppy!

Funny toys
Size: Critter Zoo, Color: 5 Different Animals
Fun toy for our 90 pound doodle, but don’t expect them to last forever. Goofy eyes and features make it a fun toy. If a big dog sits down with it, they will be able to pull it apart. The bird lasted about 5 days with solid supervision. Let’s be honest, no toy is indestructible. The price and number of funny creatures makes this a good buy in my opinion.
