Keeps her occupied!
Size: Extra Small (Pack of 1), Color: Pink
It works very well when sruffed with a healthy, soft treat. It keeps our little teething scamp busy for a while and stops her from chewing on household items including her humans!

Teeny Tiny Terrific Toy
Size: Extra Small (Pack of 1), Color: Pink
Perfect for a mini puppy! So teeny tiny; it cracks me up looking at it!! However, my little dog (10 week old Cavapoo) absolutely loves playing with it! It’s her fav! You can stuff 2-5 tiny treats in it to keep puppy occupied and focused.

Must have for a young puppy
Size: Small (Pack of 1), Color: Blue
Very helpful for our young puppy. Cleaning it isn't the easiest, but cleaning advice is easily found online and it's worth the hassle to have a durable lasting toy around

Don’t hesitate just buy
Color: Green, Pattern Name: Puppy
My puppy loves these toys. There’s of a variety of different options to keep him occupied, and I love how each toy has ridges on them to help his little teething gums. Quality is pretty good. We’ve had them a few months and they are just now starting to fall apart.

Great Toy Set for Teething Puppies
Color: Green, Pattern Name: Puppy
This is a great starter pack for puppies! It helped my teething puppy a lot, and honestly you can’t beat the variety of toys you get for the price. The quality of the chews was good as well, and it kept my puppy busy. Definitely a great value for new puppy owners.
