Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.

Perfect Dog Toys!
Color: Regular Ball Multi-color, Size: Medium
My dogs absolutely love these! My problem was I have two (of 4) that play ball. One is 15#'s and the other is 40#'s. So, I couldn't decide on the size. I decided on the medium, and they have been perfect. My smaller dog has a bit of a problem holding on to the ball, but he can get his mouth around it. For my larger dog, it's not so small I'm worried about her swallowing it. So, the size was perfect! These are thick enough neither of my tough chewers have been able to penetrate the balls, but soft enough they can easily pick them up. They have that squeak that drives my dogs nuts. The little faces on them are cute. We have spent hours playing ball with our two dogs with these balls. They absolutely love them. My small dog brings them to me constantly. Although. of the 7, it's a miracle if we know where 2 are at any given time. I actually remembered to write the review when I spotted 3 of them at the same time. My ONLY small complaint is the rubber plus dog slobber and rolling under furniture means these balls can pick up a lot of dust and hair. I have to rinse them occasionally as they can get rather gross. Luckily, they are very easy to clean with water and dry with a paper towel. Then they are as good as new! We can get right back to playing. I highly recommend these balls as you will spend hours enjoying watching your dogs play fetch. We absolutely play ball in the house, as watching the mayhem of two dogs chase the ball down hallways and across rooms in incredibly entertaining!

Only One of Two Toys That Any of My Three Dogs Will Play With
Color: Burger Shape Assorted Color, Size: Small
I can’t overemphasize this enough: My pooches just aren’t keen on toys. I don’t know why. I’ve tried everything to get them to play with SOMETHING, instead of just lying around, or begging ME to do all the work to entertain them all the time. But whenever I buy or make one for them, all three just look at me like, “Meh. Bored. Try again, Ma.” Until I bought these. I’ll spare the reader a lot of details, but for whatever reason, these little, round, mouth-sized squeakers were a hit. There’s literally nothing special about their construction or functionality at all, but my dogs think they’re great. Kinda like how kids don’t care about the fancy, expensive toy you bought them, but prefer to play with the box it came in. 🤷‍♀️ I was concerned about them getting chewed up the first day (or worse, getting swallowed), or me just being driven insane with the squeaking, but only the latter has been an issue, and only the first few days. My dogs are very diverse mixed breeds and sizes, and all three think these are the best thing ever. My medium-sized bulldog is so adorable: He very gently picks one up, squeaks it a little bit, and then runs around holding it in his mouth until he decides to drop it (usually 30 seconds or less). Then my big dog swooshes in and steals it from him (It’s a “game” that only one of them enjoys). The biggest annoyance with these is having to go pick them up wherever my poorly-trained doggos drop them (but that’s my fault, of course). In a nutshell: They’re a hit at my house. Just be vigilant the first few days to make sure your dog isn’t interested in trying to eat them.
