Great Supplement for Sticks!
Color: Dogwood Flip N Chew, Size: Medium (Pack of 1)
This is a great choice for those with furiends that LOVE to chew on sticks. The only con is that once it gets to the curved loop, they have difficulty chewing the loop due to the size of it.

My Corgi Loves These
Color: Dogwood Flip N Chew, Size: Medium (Pack of 1)
My dog loves to chew on these wooden toys. These are cheap to buy but that is because these wooden toys do not last long, and are not durable for heavy chewers. My dog enjoys gnawing on these for 30 minutes and after a few times, the wooden toy gets worn down with both ends starting to flake. I throw these out every week so he isn’t swallowing a bunch of wooden chips as he chews. However, I keep buying these because I think it’s still better than having him swallowing plastic bits from other plastic toys.

Favorite chew
Color: Dogwood Flip N Chew, Size: Medium (Pack of 1)
My pups most favorite chew ever. We call it his pacifier. The sheer joy he has when we show him there’s a new one, and the bliss he has just chewing away. Labrador—hard chewer, it lasts about 2 weeks before it’s too small to be safe.

Dogs are obsessed
Color: Dogwood Flip N Chew, Size: Medium (Pack of 1), Color: Dogwood Flip N Chew, Size: Medium (Pack of 1)
I have 2 large dogs and they are obsessed with dogwood line. I have purchased the large,super dogwood, and now the medium flip and they have all held up. They chew on them every day. They last for a long time and I have never had any problems with sharp pieces breaking off. It's a great for big chewers and they are pretty cheap to replace when they get worn. For the large and medium the shipping was pretty quick. The super dogwood always seems to take a month to get but I would still recommend.
