He was OBSESSED!!!
Size: Large, Color: Dinos Frills (Gray), Size: Large, Color: Dinos Frills (Gray)
Our year and a half old lab was excited the moment he saw it come out of the box ! He had many toys that he tore into shreds within a day so this was his first “heavy toy “ that wasn’t easy to tear . I think he loves the design and feel of it , as he carried this thing EVERYWHERE and even to bed . Him and his sister share toys but this was his , he claimed it lol Now if it wasn’t for us telling him to stop trying to kill the Dino he could have easily tore into this thing within a couple of days . However since he started chewing gently he became obsessed with the squeaker , and used that as an alarm that he was up every morning in bed 😂 The quality of the product is actually pretty good but it’s not bullet proof, and our smart dog was able to sneakily tear a whole in the nose and some how pull out the stuffing . All in all I would definitely buy another toy from this company because they are made with quality for dogs , and lasted about three weeks longer than his average toys ! It was his favorite toy 💕

Not indestructible
Size: Large, Color: Dinos Frills (Gray)
When I googled “indestructible stuffy dog toys” this popped up. My 9 month old pup loves stuffies but destroys them quickly and eats stuffing if not caught quickly. Well, this indestructible toy is cute but my dog had it torn apart in under 4 minutes so…🤷🏻‍♀️

Great for Tough chewers!
Size: Large, Color: Dinos Frills (Red)
My dog is a tough chewer and absolutely loves this toy! He was able to get a little stuffing out of the leg so far and it’s been about a week. This might sound like a short amount of time but it usually takes him under 15 mins to unstuff a large toy even if they are advertised for “tough chewers!” This is a very large size toy and would be good for any larger breed. He carries it around the house and constantly keeps his Dino with him. Since Ive found GoDog toys I’ve only been purchasing them because of their durability. I’ve tried Kong and Bark toys previously and they just do hold up long and are usually more expensive. This toy is a great value and dogs love them!

LOVE this brand. Have many of their styles. This is basically an unstuffed toy.
Size: Large, Color: Dinos Frills (Gray)
I have about 10 -12 different styles of the GoDog brand toys. It is like Xmas when my Malinois dogs get a new GoDog toy. Have loved this brand for many years and have some toys which have lasted 5-6 years -- minor "surgeries" stitch they back together -- until I retired them. They have never just worn out. Just to be clear: THESE TOYS ARE NOT CHEW PROOF. NO STUFFED TOY IS CHEW PROOF. However, this brand of stuffed toy is more chew proof than other brands. But if you are looking for a chew proof stuffed toy be advised -- IT DOES NOT EXIST!! No fabric is chew proof. Even if they invented such a fabric I would not want to ruin my dog's teeth by letting them try to chew through it. Protecting one's dog's teeth should be the highest priority. If a dog can chew through a PLASTIC KENNEL and even METAL WIRE KENNELS (yes, it happens) then they can easily chew through a puffy, fluffy stuffed toy. The "Chew Guard Technology" language may be misleading to some customers who are disappointed in the brand. I defend the brand and have used it for many years. No, I don't get paid or get free toys. Since I have had many styles within this brand and even have the pink version of this style I thought I knew what I was getting. This is basically a toy without stuffing which some people prefer. For whatever reasons my dogs prefer toys that are stuffed. Really stuffed with a firm density that they can sink their teeth into. So this toy will be OK. I can tell it will not be one of their beloved toys like some of the brand's other styles such as the purple brontosaurus. My fault for not reading more closely and assuming the grey version would be exactly like the pink version which is fully stuffed. If they get bored with these two I keep some of the Chew Guard toys stock piled. BTW one can wash and dry these toys. Yes, eventually the squeakers suck up some water and die but one can replace the squeakers. Also on Amazon. So I am willing to replace the squeakers a few times in the life time of one of these toys to be able to wash and dry them occasionally. Usually takes a couple drying cycles to get the heavily stuffed toys dried completely. If you have an aggressive chewer you may wish to look into Goughnuts dog toys or other hard rubber toys that are designed for aggressive chewers. Even then, with a determined dog, the Goughnuts toys can be chewed through. I think they offer a replacement guarantee. The other brand which has some toys of hard rubber is West Paw. An excellent brand that also offers a one time replacement. Bully Sticks are another option for chewers. PLEASE, PLEASE, PLEASE stay away from the hard plastic chew toys like the Nyla Bones. Hard plastic toys will destroy your dog's teeth over time. I learned the hard way (no pun intended) and ruined one of my dog's teeth. Vet asked if I allowed my dog to chew ROCKS !!!!!! Every tooth was cracked or fractured. Not wishing to pull teeth I had to pay for some very expensive root canals and caps. Vet's advise: If you can't dent the toy or chew with your finger nail DO NOT offer to your dog. Good advise to follow. Even some of the Bully Sticks (Costco Brand) are so hard they can chip or fracture teeth. Best for you and your dog.
