Golden Retriever puppy did not care for it but other breeds very well might
These seem to be very well made but our Goiden Retriever puppy was only interested in it for less than one minute. Before you buy i would scan the great reviews to see what breeds these really appeal to. I am sure there are some!!

Smells of smoke
The plastic smells of tobacco smoke, my puppy took one stiff and walked away. I wash them with soap trying to get the smell to go away, no change. My dog still would not even try to teethe on this. I do not recommend.

Wonderful teething toys for small teeth!
We bought these for our new three chihuahua babes and they love them so much! For now, since the babies still get really cold, we just do them as is and are going to hold off on freezing them for a bit but it's still great! They love to chew on either end and the different textures of both the rag and the different ones on the bone itself, keep them really entertained.

My god loves his new chew bone 😍
My dog loves this chew bone, he chewed on it daily since I gave it to him. It's good value for money, pretty hard, lasted about a month & a half. Good size bone for a medium sized dog
