The perfect teething toy for a puppy of any size - apparently indestructible!
Size: 9 in, Color: Large Bone, Size: 9 in, Color: Large Bone
I ordered this product for an overly excitable, destructive corgi chihuahua mix puppy, who was teething. He was a foster and managed to destroy, almost immediately, every toy I had on-hand for him, and toys I picked up at the local pet store. I was very concerned he'd swallow parts of toys, which can lead to fatal intestinal blockages, not to mention extremely high vet bills which I couldn't cover as a simple foster mom. When it arrived, I crossed my fingers that the "Seam Protection - doubled-stitched seams with heavy duty thread" would actually add "extra durability." And I was NOT disappointed! The bone shape of the toy would probably fit comfortably in the mouth of any dog or puppy, as you can see from photo #4. What's coolest about the shape of this toy is the pup can sink all of his or her teeth into it, providing comfort for the entire mouth and not just a few teeth or only one section of its mouth at a time. I was much more experienced as a kitten foster mom, and had had similar difficulties finding teething toys for kittens. This toy is thin and light weight enough that I imagine it could provide relief for little kitten mouths, also, but I didn't get to find out, as my little foster pup chose this as his #1 favorite toy and brought it with him to his forever home. I wanted to know how long it would take before he'd destroy it, though (picture 5 he'd had this Dura-Fused bone toy for a few hours short of one week, and the last photo - you'll see he'd not even undone a small portion of the seam!) Overall I would highly recommend this product for teething babies of almost any species. As far as I could tell it is indestructible. Almost seven days of constant gnawing and he'd not even taken one stitch out, created any tear or rip, let alone, gotten close to being able to swallow the squeaker (always a fear!). I imagine months later, he's still been unsuccessful at ripping/tearing this toy at all. I'd gladly buy again should I foster any dog or puppy - the company lives up to its moniker, Ethical Products, because they've produced a no-frills and apparently indestructible squeak toy which I'd have no fears of leaving with a teething puppy unsupervised. Highly recommended!

Good tug toy
Size: 15 in, Color: Retriever
I have a doberman that shready everything in 2.5 seconds. This lasted a few days so was impressed for the cost. Would buy again as he really liked it.

My dog’s new favorite
Size: 8 in, Color: Squirrel
didn’t expect much for the price but my dog actually loves this thing. It’s tough enough to hold up to regular chewing and the leather gives it a nice texture that’s different from the usual plush toys. He carries it around like it’s his prize. It’s not indestructible and if your dog is a heavy shredder it probably won’t last forever but for moderate chewers it holds up way better than a lot of toys I’ve tried. Definitely worth grabbing again.

Not for gnawers
Size: 11.5 in, Color: Bear
I was hoping this would work for my teenage ACD and save my leather goods from being chewed on.
He gnawed on it quietly I was thrilled. But I had to take it from him within a few minutes. Gnawing apparently equals chewing pieces off.
Not made for chewers or gnawers.
It seemed to be well made, was soft, was actually a fairly good size and didn’t get gross when it got spitty. Just didn’t work out for Captain chaos destructor of all.

Durable & Leather. For Small-Medium Dogs
Size: 15 in, Color: Retriever, Size: 15 in, Color: Retriever
This is a great dog toy! My Pomeranian is a small guy at only 8lbs. but he sure knows how to chew and he does it as often as he can. I was throwing out toy after toy because he was tearing them to pieces after only a half hour or so. After putting my money in the garbage so many times, I decided to search for toys that would hold up to his destructive mouth. I found a lot that claimed they wouldn't fall apart but they were all more than I wanted to spend. I came across this toy and a rabbit shaped one just like this. I bought both months ago and both are still in tact after all this time. Sure the edges are a little frayed but other than that, no damage whatsoever! I'm not sure what dura fused means but that seemed promising to me when I was reading the description, also the fact that they're leather made them seem more durable to me. Both have squeakers inside and some sort of stuffing as well. I throw all of my dogs toys in the laundry or hand wash them once a week, except for these. When these toys get wet with my dogs saliva, they look like they're not meant to get wet. Even without washing, these seem fine. This toy is probably about 9" long or so if I had to guess. In my opinion, it'd be perfect for a medium sized dog. It's a tiny bit big for my little guy but he manages just fine! If you're looking for a durable toy that your small to medium dog can chew on constantly, look no further!
