Perfect for Teething Puppies and Adult Dogs and Keeps Them Busy
Color: Pacifier, Size: Small, Color: Pacifier, Size: Small
The Nylabone Puppy Pacifier Chew Toy has been a lifesaver during my puppy’s teething stage and AFTER.
Quality: The material is sturdy yet gentle enough for developing puppy teeth. After weeks of daily use, it shows normal wear. The pacifier shape makes it easy for small mouths to grip and carry around.
Effectiveness: It’s great for soothing sore gums and redirecting chewing behavior. I’ve noticed my puppy is calmer after chewing on it for a while.
Helpfulness Tip: Supervise during chewing sessions and wash it occasionally with warm soapy water to keep it clean.
If you have a small-breed puppy under 25 lbs, this toy is a safe, durable, and fun way to help with teething.
Bought twice, they love these. Miniature dachshund and French bulldog

Nice chew toy
Color: Dinosaur, Size: Small
I have a small dog that loves chewing on these. It’s a bit pricey, but it helps keep her teeth clean, so I will pay this over her needing tooth extractions and a vet bill.

Not chew proof for little puppies
Color: Rings, Size: Small
Our first Chihuahua when she was a puppy loved chewing on this and pieces never came off. Our second Chihuahua I guess was a heavier tour and he was able to get pieces flaked off.

Great for teething puppy
Color: Pacifier, Size: Small
I was trying to find something very sturdy for our puppy that she could not bite pieces off of and this toy has been great. She loves it and it has held up very nicely. They are not soft so it is great for our teething pup. They are also the perfect size if you have a bigger pup like we do. She is a 4 month old pit mix. I would say they would be too big for a small breed puppy
