Pups love these sneakers
Color: Squirrels (3-pack)
My pups really enjoy these toys—they love the squeakers and stay entertained chasing them around. Perfect size for small dogs and puppies, and they’re soft enough for indoor play. The only downside is they don’t hold up forever with heavy chewing, but for the price and fun factor, they’re definitely worth it.

Good for a small to medium dog
Color: Squirrels (3-pack)
These replacement ones were bigger than anticipated but work well for my small dog. Pretty durable (and she likes to destroy toys)

Perfect Toy for the Picky Dogs!
Color: Squirrels (3-pack)
These are replacement squirrels. I had these for my own dogs. When I noticed how much enjoyment they got out of them, I purchased them as gifts.
My brother’s 20 lb dog is so picky, but I took a chance. The squirrel toys are the only ones he plays with. According to my brother, his dog ignores treats and toys, but loves the squirrels.
A friend of mine said the same thing. She also has small dogs, 25 lb & 30 lb. They preferred the squirrels.
This toy is not for big dogs. Unless they’re gentle, they will probably be torn apart very quickly.
They are very easy to chew on, the squeak isn’t loud, there’s no smell and very entertaining!

Dog Approved
Color: Squirrels (3-pack)
The toys are soft but well made, and my dog really likes that they squeak. He loves carrying them around and hunting for them when I hide them.
