Fun, engaging, and cute toy for dogs!
Color: Yellow - Fish Skewer, Color: Yellow - Fish Skewer
I got the fried fish toy for my dog. So far, he really enjoys the squeaking noise and comes running every time he hears it. The toy material is pretty thick and is holding up well during playtime. The size of this toy is perfect for my small dog but it might be a bit small for larger dogs. Overall it's a fun and super cute toy for my pets that's become a favorite!

Fun enrichment
Color: Yellow - Fish Skewer, Color: Yellow - Fish Skewer
Bought this to keep my dog busy while I’m out, and surprisingly it works. It’s soft, lightweight, and he was interested right away. Hiding treats inside turns it into a sniffing challenge that keeps him occupied longer than expected. The squeaker does its job, and the material feels gentle, but this is not for heavy chewers. If your dog destroys toys for sport, proceed with caution. Overall, it’s a fun enrichment toy that helps with boredom. Great for light to moderate play and dogs who don’t choose violence every day.

Really cute and great for photos
Color: Yellow - Fried Chicken Leg, Color: Yellow - Fried Chicken Leg
This drumstick plush toy is super cute and looks great in pictures. My dog liked it right away and keeps carrying it around. It’s soft, lightweight, and the size is just right. We’ve already taken a few fun photos with it, and it would also make a nice little gift for someone with a dog. Simple, well made, and definitely worth it.

Don't Bother Unless You Have Something The Size of a Chihuahua
Color: Yellow - Fried Chicken Leg
Title is definitely deceiving. We have 2 Pitbulls and a Bull Terrier. They simply looked at this thing and it blew into pieces. These are more for smaller dogs. I wouldn't even say medium. It was just a big disappointment. I was excited to give them this toy, until it arrived and I saw how small it was.

Tiny
Color: Yellow - Fried Chicken Leg
Was disappointed. The toy is tiny. I don’t think a puppy could use it. The design was great, except for the size.
