My dogs love this toy!
Style: Rabbit
My small dogs Love this toy. They each bring me bunnies all day long. One bunny already has a little tear in it but easy to stitch. I'll see how long the toy lasts. So far it keeps them happy & busy.

Sturdy, cute and practical.
Style: Squirrel
These are so cute and practical. I have 2 mini schnauzer puppies and they are addicted to this play. It comes with 5 squirrels. They dig and smush into the holes in the tree to get the squirrels out. I throw them around and they play and then I put all the squirrels back in the tree. Again, they go right back to the process of smushing and digging around to get them back out. ALL the squirrels squeak! Excellent item, very sturdy tree and the squirrels can withstand quite a bit of aggressive play. (I've had to sew them a couple times)

Durable and adorable
Style: Turtle
Big dogs need love too. My boy is a Lab/Pyrenees mix and he carries his babies around everywhere. He is so gentle with them. He loves to get them out of their house, and keeps him busy mentally and physically. They are definitely indoor toys, but I would highly recommend these if you have a fur baby that gets a favorite toy and cares for the special toys for a long time. The only down side is the external stuffed “house” rips apart so we are left with the little bunnies, squirrels and turtles without their homes.

Little dogs get overwhelmed
Style: Squirrel
It’s as described but my dog won’t play with it, I think it’s a bit overwhelming for a 5 lb yorkiepoo. She loves the squirrels individually but won’t pull them out of the toy stump. It’s made well and good quality.

Such a cute toy that my dog loves ! Yellow is her favorite and when she saw this she instantly gleamed with joy! I love that the dogs can also dig to find the bees which for a dachshund owner helped keeping her a busy bee
