Perfect size for small dogs to play solo or gentle tug of war.
Color: Alligator(Green)
I ordered this toy for my dog. She is a 13 pound Shih Tzu mix The toy has nice soft fluffy, short fur and a mix of different textures that I feel when she’s playing with it helps keep her teeth clean. She loves the squeakers. She loves to squeak squeakers!! The tail is great for playing a gentle game of tug-of-war. I know she enjoys this toy because whenever she wants to play, she’ll bring it over to me and pop it in my lap. If I don’t respond, she’ll start pawing on my leg until I acknowledge her. Whether I throw it across the room or engaged in some tug-of-war, it keeps her entertained & stimulated. A great boredom buster! She’s been playing with it now for over a month and so far the squeaker still squeaks, and there are no holes or tears in the toy.

Dog didn’t like sound it makes
Color: Duck(Yellow)
I ordered the duck. It’s yellow and a good size for small to medium dogs. It is well made but as the information states this is for gentle chewers. I have a yorkie poo who thinks he is a big dog and likes toys bigger than himself and this fit the bill until…he heard the sound it makes. He didn’t like it and now refuses to play with it. 🤷🏻‍♀️ So the 4 stars because he did like it and did play with it. Minus one because of the sound he doesn’t care for. I will need to cut it open if I want him to play with it again. As of right now he doesn’t want to get near it.

Not actually for aggressive chewers
Color: Alligator(Green)
*sigh* Yet ANOTHER toy that's marketed for aggressive chewers that doesn't live up to its claims. My 50-lb goldendoodle put a hole in the plush part of this alligator toy in under 3 minutes, and that was just from normal chewing and not the tooth gnashing with her molars that she usually does. So why 5 stars still? Because after that initial hole was created, we've asked her to be gentle with it, and she's done a fairly good job, leading to a toy that is still intact that she absolutely LOVES. No kidding, this is her new favorite "baby," although I do suspect that the next new toy she gets will then become her new favorite. Kids, amirite? Anyway, I suspect that she loves this toy so much (aside from the fact that it's the newest one) because it's kind of like 2 toys in 1. She has a large rope toy that she adores and only gets to play with when closely supervised because otherwise she uses her teeth to effectively cut through all of the individual rope strings in no time flat. This kind of mimics that texture, but she gets to play with this one to her heart's content and so far hasn't done any appreciable damage to it. She also loves the texture of plush toys, and this one is large enough that she can really grab it in her mouth, but not so big that it takes any effort to carry around. The squeaker has somehow managed to remain alive, and I attribute that to her being asked to be more gentle with this toy, since usually, the reason why she's making holes in plushies is to dig that most cherished little plastic squeaker out of her toys' guts. This is actually a pretty expensive dog toy, though the current coupon price brings it to just under $15, which seems more reasonable, but still kind of pricey for something that your dog may chew completely through in 10 minutes. If you don't have an aggressive chewer, this is a pretty great toy. If you do, be prepared to pay for a toy that will become a pile of innards in pretty short order.

Well-Made Toy That My Dog Loves, Great Quality and Fun
Color: Alligator(Green), Color: Alligator(Green)
This dog toy has been a great addition to our pup’s collection. It’s well made and feels like solid quality that will stand up to regular play, which is exactly what you want rather than something that falls apart after a few uses. My Havanese absolutely loves it. The size is just right for small to medium-sized dogs, and we’ve had a lot of fun with tug-of-war and gentle fetch sessions. The texture and feel give her something satisfying to bite and carry around. Pros: Well made and durable, feels like it will last through many play sessions. Great size for small to medium dogs like my Havanese. Encourages play and interaction, perfect for tug-of-war and light fetch. Nice value for the quality and price. Easy to grip for both dog and human hands. Cons: Not ideal for extreme chewers; if your dog loves to destroy toys quickly, you might need a super-heavy-duty option. A bit simple in design, no squeaker, but that’s just personal preference. Overall, this is a solid, fun toy that delivers on quality and performance, and my dog genuinely enjoys it. Highly recommend. Still gets 5 stars!
