Perfect Teething Toy for Puppies!
Color: Pacifier, Size: Small
My puppy absolutely loves this Nylabone Puppy Pacifier Chew Toy! The bacon flavor immediately caught his attention, and it has quickly become his favorite toy. It’s the perfect size for small puppies and easy for little mouths to carry around and chew on.
The material is soft enough for teething but still durable enough to hold up to daily chewing. It has really helped redirect my puppy from chewing on furniture and shoes, and it seems to soothe his gums while he’s teething. I also like that it keeps him entertained for long periods of time.
Great quality, puppy-approved, and definitely worth buying for any small dog owner!

My dogs love these
Color: Pacifier, Size: Small, Color: Pacifier, Size: Small
These are my dogs favorite toys and they keep them entertained for hours. Yes they are able to chew them down to small pieces but they are sturdy enough where they won't swallow them. I have miniature dachshunds so small dogs.

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
