Great with supervision
Size: 6 Inch, Color: Bone
My dogs LOVE these, but removing a star because these apparently are VERY delicious and they will ingest what they rip off if I don’t supervise; also removing a star for how quick they’re able to tear these up. These are like catnip for dogs, I’ll still buy them!

Don't waste your money!!
Size: 5 Inch, Color: Fox
With in minutes my puppy was pulling on the middle fiber stuff. I was worried he would choke/ingest it so I immediately threw it away just like the money I apparently threw away on this unsafe and misleading chew toy.

Very Nice squeaky toys!!
Size: For Medium and Large Breed, Color: 6 Pack
6 in a pack, very cute looking, my 10month golden retriever gnawed off the tail of one in 10min. Then took a while to chew open the head and take out the squeaker. He was given 2 toys so far and in both he gnawed open the head and removed the squeakers. The brown one looked like a real dead animal that was run over by a car.. flat body and busted open head.. gruesome!
inside the body is a sheet of sturdy plastic that makes a crinkle sound.
Overall very good, wont last long if you have a dog that likes to chew.. but at least there are 6 of them.
watch out for ripping off tails or feet.. those are ALWAYS weak points on all of these stuffed/nontsuffed animal toys and can be swallowed. They should just make an oval and have the feet an tail drawn on. also watch out for when they open the head.. the squeaker can easily be swallowed.

My dog LOVES to destroy these
Size: For Medium and Large Breed, Color: 6 Pack, Size: For Medium and Large Breed, Color: 6 Pack
I have a black lab/pitbull mix. She is a very destructive puppy when it comes to her toys. I have tried the "indestructible" toys but they were never indestructible enough and my pup didn't enjoy them. But these... lol. When she gets a new one from the box she loves playing tug of war, playing with the squeakers in the head and the tail (to a nauseating degree), and proudly prances around with her new toy to show everyone. But once that phase passes she gets down to business, tearing at it until she gets the squeakers and crinkly paper out. Thankfully she has no interest in the inner parts of this toy, so once she's done with it I just pick up the squeakers and paper/plastic to throw them out, then it becomes a tug of war toy again until it's time for the "stuffy graveyard". Then we start all over again with a new one (the lifespan is between 3 to 14 days). I've purchased this product 7 times already and will continue to purchase more as long as my doggo loves them. If you've made it this far, sadly these toys can be destroyed if you have a power chewer like my pup, but these toys are cheap by comparison to the "indestructible" toys so they are easily replaceable and don't break the bank. These can be great toys for the right dog.

Well made and great for tug of war with the dogs

The puppies love these toys. I have no idea what the blue one is supposed to be but they are very cute and seem to be holding up well.
