Gave my dog an allergic reaction
Color: Blue, Size: 4.5 Inch
I have one that has lasted 2 years of hard play, very durable. However, this newest one in the teal color gave my dog an allergic reaction. Her face and eyes swelled up within 1/2 of playing with it. So I threw it out. I have had no issues with the green one that I bought yesterday ago.

The best gift for new dog owners
Color: Blue, Size: 4.5 Inch
This has been my mom's go-to toy to gift to friends and family when they get a new dog. I just followed suit and bought one as a gift for my friend's Newfoundland puppy. Versatile, can be used as a ball or tug of war toy, and can buy a bigger size for a puppy to grow into because they can still grab it by the holes, unlike other balls and toys that are just too big to get their mouth around

They know the word "treatball"
My dogs love these treat balls. I give them one after each meal as a "dessert". I think it helps clean their teeth also, and it keeps them busy for a while.

Highly Recommend!!!
I bought a second set of these toys for my puppy who is a Chorkie because he LOVES them! They're super durable, very bouncy, extremely light weight, soft and flexible. They're the same size as a golf ball so they're perfect for small dogs. I would highly recommend these especially if you have a puppy who likes to chew and play fetch.

Perfect size and very durable! Flexible but sturdy.
Perfect for my Frenchton puppy. Easy to pick up in her mouth and they are flexible but sturdy. Unfortunately lost all three already, lol, so guess I’ll be buying more. 🤦‍♀️
