Dog ends up eating plastic ends
Size: For Medium Dog, Color: Grassgreen
At first I thought this would be a great toy but in reality the design doesn’t make sense. The little pieces ‘pricks’ of the cactus get chewed off and swallowed by the dog. So you’re essentially feeding them plastic.

AMAZING for my Doberman
Size: For Medium Dog, Color: Grassgreen, Size: For Medium Dog, Color: Grassgreen
This toy is the absolute BEST! It has out lasted every other toy by a long shot. So far it has lasted 7 months with a very tough chewer. No other toy has lasted more than a week or two aside from this one. I got this the same week I got my Doberman puppy. I am very impressed how well it has lasted so far. It’s still in great shape but is missing some of the “spikes” and has some tooth indents. Squeezer still works well too. It’s one of his favorite toys.

My Puppy Loves this Indestructible Dragon
Size: Large, Color: Pink, Size: Large, Color: Pink
My puppy (8 month old black lab mix) loves, loves, loves her dragon. She has had it for 2 months now. It is one of her favorites and gets daily rough play time. It's her go-to toy for fetch and tug games, as well as just general mouthy play. The squeaker gave out after about 4 weeks, but she would binge squeak for prolonged periods (kind of like chomping on gum) so it was almost a blessing when it went silent. She still chomps on it, but at least now I don't have to hear it. Other than the fact that it's a little grungy and bedraggled from so much loving, it is still in amazing shape. The seams and fur are all still intact. There are no visible holes, rips, or weak spots. I love Chew Guard Technology.
This dragon replaced her goDog Iguana (from PetSmart) that developed a tear in the fur after about 4 months of heavy use. (It was superficial, just the outer fur layer and not the innards, but we disposed of it before she could eat more fur.) She can be pretty rough on her toys and I can never predict if any given toy will last minutes or months. The goDog stuffies definitely fall into the "months" category, even with rough daily use.
Edit: The dragon lasted about 6 months of intensive, hard play before it developed a small tear in the fur. I patched it a couple times, but once my pup discovers a weak spot, it's the kiss of death for any stuffed item. We had to dispose of the dragon (so sad) to keep her from eating any more of the fur. We replaced the dragon with the goDog Chameleon, which is still going strong. I think we will go back to the dragon for our next toy because it's just so darned cute. We gave the dragon to my niece for her golden retriever puppy who is very chew-happy. That dragon is also doing well. You've just gotta love that chew-guard technology. This is one tough toy.

Indestructible Toys My Dobermans ❤️
Size: Large, Color: Mesh Green
Actually Respect! goDog Is a Lifesaver
The variety of size and colors are phenomenal 😇
I have two Dobermans — serious, determined power chewers — and I’ve spent years trying to find toys that survive even a few days.
I’ve tried the big brands (Kong, Goughnuts, Jolly Ball, you name it) — and while some toys last a little while, almost everything eventually ends up shredded, de-squeaked, or in pieces.
goDog toys are the ONLY plush toys my Dobermans won’t destroy.
We own multiple goDog toys now — dragons, dinosaurs, lizards — mostly in the large size (perfect for Dobermans), but even a few medium-sized ones hold up surprisingly well.
Here’s what’s amazing:
• They love them — actually carry them around, toss them, chew them gently, and squeak them happily.
• They do not rip them apart — no matter how much tugging, chewing, or wrestling happens.
• Large sizes are best for Dobermans (and other big breeds) — but even mediums survive for calmer play sessions.
• No ripped seams, no stuffing everywhere, and no destroyed squeakers after months of use.
What makes goDog toys different?
The secret is their Chew Guard Technology —
• A reinforced, high-strength inner mesh layer under the soft plush
• Double-stitched seams
• Durable yet flexible material that somehow resists punctures, tears, and brutal shaking
The outside stays soft and fun, but the inside is built like armor.
It’s NOT a super hard rubber or rough canvas — it still feels like a cuddle toy, but it’s engineered to survive serious chewing.
Materials include:
• Durable polyester plush
• Chew Guard inner lining (high-tensile mesh fabric)
• Reinforced stitching
• Non-toxic squeakers
• Safe for dogs to play with long-term
Real Owner Advice:
• Always size up if you have a heavy chewer — large sizes are a must for Dobermans or similarly strong breeds.
• Medium sizes are fine if you supervise or your dog is more moderate with toys, but the large toys are built tougher overall.
Final Thoughts:
If you have big dogs, strong jaws, or just tired of wasting money on destroyed toys — goDog toys are a must.
No other plush-style toy even comes close.
My Dobermans will destroy almost anything… but they treat their goDog toys like treasured companions. No holes, no rips, just happy dogs.
