Nice burrow toy for small to med dog
Style: Popcorn Bucket
We like it! He loves to dig into stuff so this is a perfect addition to his other burrow toys. The most compact and only one hole makes it somewhat challenging for him.

a fun toy!
Style: Popcorn Bucket
My dog absolutely loves this toy! I have to repeatedly stuff the pieces back inside so he can pull them out. That being said, if you have a heavy chewer this one will bite the dust pretty quick. It’s cute but not sturdy for chewers.

Perfect for keeping energetic pups busy, mentally stimulated, and happy!
Style: Milk & Cookies
I bought this interactive dog toy to keep my puppy mentally stimulated and it has been a huge hit! At first i was worried she wouldn't understand the concept but once i started squeaking the cookies inside the milk container she couldn't stop poking around until she was able to get all three cookies out. Trying to get the cookies out keeps her entertained but even after she gets them out she loves running around chewing and squeaking on the cookies. The milk container has holes just big enough to make her work a little but not get too frustrated, and the cookies are durable enough for her to keep chewing on without chewing right through them and without her hurting herself on them. Plus cleanup is easy too they wash quickly in warm water. Since the cookies are pretty small they can easily get lost under couches or beds.

My Cattle dog mix loves these!
Style: Popcorn Bucket
For a hyperactive super smart dog, this popcorn puzzle is a great treat! This is her second and she still plays with her first. I'm going to go ahead and probably buy her some other versions of puzzle toys. This is a good one. Buy it.

Needs to sell replacement popcorns
Style: Popcorn Bucket
My dog love this toy however, we have 5 popcorn buckets and only two popcorn balls left. It would be great if there was way to just buy the replacement popcorns. I haven't found them anywhere though.
