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.

Hands down, the best dog toys on the Planet!
Color: Burger Shape Assorted Color, Size: Small
Our Miniature Pinscher absolutely loves squeak toys. We tend to get those long-bodied, no-stuffing animals which are great for tug-a-war, but on her own, she rips these suckers apart and removes the squeaker within a day of owning it. I occasionally buy a big bag of just squeakers and hide them in shoes and what not, but those have a 5 minute life span as she'll pull the little whistle right out. These latex squeak toys are a total blessing. They're super well made and just the perfect dog toy. We've had them a week, and she's been playing with two out of the package and not a tear or rip. The squeaker is very loud and the material is impossible to rip. She's getting tons of exercise running around the house with these things, and loves when I throw 'em. Love the colors and faces on the burger style. Easily the best dog toy on Amazon and we've been through 5 years worth of purchases.

Great ball for small dog (3.5 pounds)
Color: Burger Shape Assorted Color, Size: Small
I have been looking for a ball that my 3.5 pound Maltese puppy can enjoy. Up until now it was small balls were difficult for my little Rosie to grab. These balls at first seemed to be too big. But after a few minutes Rosie grabbed one of the balls in her mouth and has been crazy for these balls ever since. They collapse so she can get her mouth on it. They squeak each time she bites down. When I toss the ball, they bounce around like crazy and make a squeaking sound. They are so soft that it would be difficult to break anything. Also since they are not round, they do not roll under furniture most of the time. I uploaded a video of my little Rosie fetching one of these balls. Great toy!

Dog doesn't chase balls but does chase these!
Color: Regular Ball Multi-color, Size: Medium
This is a great product. My Aussie mix won't chase regular balls, but will chase these for long periods of time. Its the only way I can get him excercise right now. He holds them in his mouth constantly and has lost interest in his kong stuffed toys. This is my second time buying. The first time was great but the second batch had hardly any sqeak and not much air. Seller- please check your quality control! I have to go to another seller if these aren't consistent, because my dog needs the squeak in order to be interested.
