Cute but not Durable
Color: Squeaky Corn Dog Toys
It’s a very cute dog toy but for it being labeled for “aggressive chewers” I thought it would last longer than 3 days here.. I now have small chunks of “corn” all over my house and had to throw this toy away.

My dog loves these
Color: Squeaky Corn Dog Toys
I have a healer and he loves his corn. He does go through them every couple months but he’s a very aggressive chewer. He mostly loves to play catch with them. I have ordered many of these.

Kind of hilarious
Color: Squeaky Corn Dog Toys
I bought this for my golden puppy during peak teething time, and she showed no interest for 2 more months before becoming obsessed with it. It squeaks pretty loud & she appears to enjoy that. She also carries it while running by the rope end and flails it around to play lol. Worth it.

Great for frenchies
Color: Squeaky Corn Dog Toys
Really nice toy, my dog loved it until it broke, really good for frenchies! It’s a great cheap toy but the knots get chewed through.

Tasty Treat
Flavor Name: Variety, Size: 3 Count (Pack of 1)
Puppies loved these! Unfortunately, they liked so much- didn’t last as long as anticipated. We have more aggressive chores than I thought 🙃
