Good product misleading size.
Size: Small (Pack of 1), Color: Blue
Really disappointed about the size. It is way too small for my berniedoodle. He still likes it for play but I’m afraid he might swallow it. It’s very sturdy tho and is chew resistant. I guess I didn’t pay attention to the size. Looked big in the picture.

Must have item for dogs!!!
Size: Medium (Pack of 1), Color: Pink
The puppy kong is a must have item for every new puppy owner. Super cute!! They usually will last forever (unless you have a super chewer then you need the black one). Great value!! Keeps the puppy busy and entertained. Especially when frozen. Google and the Kong website have tons of recipes. I tend to stick with a little bit of kibble some mashed banana and peanut butter. Also, good options are jars or pouches of baby food just make sure you check the label to ensure there is nothing toxic to dogs in it. More options are kibble soaked in water or broth, pumpkin puree, green beans and carrots. I could go on forever. If you own a dog, a Kong is a must have! I always have two ready to go. And they are dishwasher safe!

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.
