Not for low food-drive dogs
Style: Chase & Treat
Not the right toy for us but maybe for others. Seems durable and is on the more affordable side. However, the Velcro is so strong that it’s difficult and/or uncomfortable for our dog to open it. May be better suited for a more food-driven dog.

Multi variant review!
Style: Tuggi Ball
Coachi Tuggi Ball - Great handle, ball is too big for puppies for sure and unsure on how about the hardness, it is hard, like a hard styrofoam Chase and Krinkle - excellent, buy. Soft for puppies to latch on and the fur plus krinkle keeps them super engaged. Great handle too. Length, you can play with Felt tugs are good too. These have been good minus the ball tug lulz

Odd toy but Perfect!
Style: Chase & Crinkle
Our dogs love this toy! I love that the leash on it is a great size for playing with them. The crinkly noise is my collie’s favorite toy noise so it gets her so excited, and while I’m recovering from surgery, I can’t play rough or bend over to pick up toys from the floor. With this, I can play a watered down version of a flirt pole with her and the corgi and they love it! I appreciate how strong and quality the leash strap feels - I don’t have to worry about it failing quickly, and the padding inside the handle makes playing so much more comfortable. For me, it’s been worth every penny.

Soft and easy to grab. Dog loves the tassles
Style: Tuggi Tug
My dogs are tugging fools and they love this toy. My puppy isn't food motivated so this is his reward when training. It's thick so he doesn't chew through it but it's still easy to hold. The colors are bright and it's soft and easy for him to get ahold of. The only problem is getting him to let go! I wouldn't leave it down for him to chew because he'd chew right through it, but used as a tug toy it's perfect. It's dog approved!

Fun, Durable Balls for smaller heavy chewers
Color: Four colors, Size: 5cm (ball only)
Perfect size and strength for my small dog that is a heavy chewer! She hasn’t been able to destroy and chew up this one like she has with every other toy! Definitely chew resistant.
