Gave this to my 11 week old pittie, and she did significant damage within 15 mins. She left a pile of chewed bits on the couch but thankfully didn't eat them. Definitely don't leave unsupervised. That said, she LOVED it and it seemed to help her teething gums so, I'm still giving it a 4/5 Puppy pics for tax

FOR SHORT TIME USE

Size: X-Small, Color: Ring Bone

My puppies love this. After a couple of weeks, it is worn so I throw it out and buy another since it's reasonably priced. I don't want them to actually ingest a chunk of this.

Great for our puppy

Size: X-Small, Color: Ring Bone

This chew toy has quickly become our puppy’s absolute favorite. She’s just starting to teethe, and keeping her busy and comfortable has definitely been a challenge, but this ring has been a lifesaver. She was interested in it right away and keeps coming back to it on her own, which is a huge win. The chicken flavor seems to really hold her attention, and it gives her something appropriate to chew instead of everything else. It’s the perfect size for a very young puppy and easy for her to hold and gnaw on without getting frustrated. It keeps her occupied, helps soothe her gums, and gives us a much-needed break during those teething moments. If you have a puppy just starting the teething phase and need something safe, durable, and engaging, this is an excellent choice and one I’d happily buy again.

Nylabone Ring Bone

Size: X-Small, Color: Ring Bone

My dog loves these. She chews them into pieces which helps keep her teeth clean. It is a mess to clean up. She chews and spits out the pieces. She is 6 years old so not a puppy.
