Toughest toys around!!!
Color: Gorilla, Size: Small
After 30 years of shopping for dog toys & endless nights of sewing them back together, those days are over thanks to this brand of toys!
These get taken outside where they are brutally tugged, twisted, snatched, tossed and shaken to no end by our 58lb black mouth cur & 80lb Shepherd Retriever mix.
Most times they bring them back in the house but 2 of them they keep outside in the scorching Florida sun & rain & they're still tough as can be! The only damage these 2 toy punishers have managed to do is occasionally kill a squeaky inside (after about a year or more) & eventually the ones they will keep outside they have managed to get the black trim piece that goes around the outside edge to come off in a small section but it's still hanging on the toy flapping around smacking them in the face (which our black mouth cur love's,lol).
I first bought 2 small ones (yellow duck & pink pig) Christmas 2020. They held up so well that a few months later I bought the fox, dog & purple gecko. We also have the gorilla, snake, green gator (their favorite right now), orange gecko, a 2nd duck, raccoon & a few others I can't think of right now. The glorious thing is I haven't had to sew a single toy in over 2 years & I don't have to worry about my girls getting too rough with them when playing & the best part is not having to worry about them defluffing them & ingesting it or choking on it especially when I'm not at home. I don't have to pick them up before leaving to ensure they are safe. They can continue to terrorize the house playing with these even when we're not there & the only thing I have to worry about is what are they going to break when they sling one of these across the room. This brand is the only brand of dog toy we buy now. We have not had to throw any of them that we've bought away either & the cost is perfect for the value that you definitely get!

The only toy my dog wants
Color: Gator, Size: Large, Color: Gator, Size: Large
I have a 9 year old, 12 pound chihuahua, and this toy is everything to him. Ever since he was a tiny puppy, he’s liked toys that are at least as big as he is. Once I got him this, it was the only toy he’d play with. He carries it everywhere. He likes to chew on it, and sometimes pulls apart the threads. He LOVES to play tug of war with it, so the handle is awesome. It has so many squeakers, which is also a plus, and it holds up well for our little guy. We’ve probably had at least 10 of this same toy, we get him a new one about once a year when it starts to get worn. I worry that if they ever stop making it, he’ll be depressed lol. It’s been with him at all life stages and he doesn’t go anywhere without it. Really can’t ask for more when your dog loves a toy this much

Lots of squeakers in this one!
Color: Gator, Size: Large
Our rescue dog is a power chewer so this one doesn't last long, but I still gave 5 stars because it's not advertised for power chewers, so I knew what we were getting when we bought it. So why did I buy this for our dog? The number of squeakers... the dog goes nuts for those and it makes the toy last longer because she will only play with the ones that still squeak.

NOT for aggressive chewers!
Color: Lion, Size: Medium
My aggressive chewer had destroyed this in 3 minutes! Chewed off the ears, and chewed apart the body to try to get to the squeaker - it was in the trash 5 minutes after I gave it to him! Yes, the seams are tough, but he easily chewed around them. Don’t buy this if your dog is an aggressive chewer!

Somewhat durable.
Color: Elephant, Size: Small
My dog loves these toys, I think it's the squeaker. I've tried several and this elephant one holds up the best.
