Happy puppy with this durable bone
Size: X-Small, Color: Pink
Our new puppy loves the texture and thickness of this bone. She is an aggressive chewed and has not yet destroyed this bone. We have purchased Nylabones for our dogs year after year and have had several happy puppies over the years.

Great for a teething puppy
Size: Small, Color: Pink
This is one of the best training collars we have used. So good that we ordered a second one so each dog has one and we have recommended it to several other people. It has 3 options, beeping, vibration and shock. Each option has several different settings. The collar comes in many different colors. It is very sturdy and it is waterproof. It is adjustable and the clip is very sturdy. I had previously bought a different training collar that did not phase my dog in the slightest and was a complete waste of money. It always seemed to be low on battery even after charging, this one however lasts like a week after charging. I will continue to use this brand for sure

The Toy Annie Always Comes Back To
Size: X-Small, Color: Pink
⭐⭐⭐⭐⭐
These have become one of Annie's all-time favorite toys.
Annie is a tiny 4-pound dog, and she can be surprisingly picky about toys. She has a basket full of options, but she consistently comes back to her nubby Nylabones.
I think the size and texture are a big part of why she likes them so much. They're easy for her to carry around, chew on, and play with by herself. Whenever I buy a new one, it quickly becomes part of her regular toy rotation.
As a small-dog owner, I appreciate finding toys that are appropriately sized and actually get used instead of being ignored after a few days.
If you have a tiny dog who loves to chew, these are definitely worth trying. They've been a favorite in our house for a long time.

Dogs love these!
Size: Small, Color: Pink
My miniature Goldendoodle puppies love these! The only drawback is after several weeks of chewing, the bones develop pretty sharp edges long before the actual bone has been worn down. At that point, they are dangerous for the dog’s gums and must be thrown away.
