My pup loves her Kong
Size: Small (Pack of 1), Product Packaging: Standard Packaging, Size: Small (Pack of 1), Product Packaging: Standard Packaging
My little pup loves her Kong! She’s about 14 pounds so I recommend any dog with that size to get the small size. The quality is great. Extremely durable, but still workable enough for her to get in and find all the goodness!

KONG Classic Stuffable Dog Toy
Size: Large (Pack of 1), Product Packaging: Standard Packaging
The KONG Classic is one of those toys that actually earns its reputation. It’s tough, reliable, and keeps a dog busy in a way that feels genuinely useful. Stuff it with treats, peanut butter, or kibble, and it turns into a solid boredom‑buster. Even after plenty of chewing and tossing around, it holds up without tearing or cracking. ⭐ What Makes It Great Extremely durable — perfect for strong chewers Great for mental stimulation when stuffed with treats Easy to clean compared to other stuffable toys Bounces unpredictably, which keeps dogs engaged Long‑lasting value since it doesn’t wear out quickly ⭐ Bottom Line A classic for a reason. If you want a toy that keeps your dog entertained, withstands heavy chewing, and works as a treat puzzle, the KONG Classic is a dependable choice that actually delivers.

Great for freezing apple sauce, peanut butter, etc for a treat.
Size: Large (Pack of 1), Product Packaging: Standard Packaging
Our dog has extreme separation anxiety. When ever he even thinks we are going to leave he barks and jumps in our face. He is a mini Aussie, so he can jump high. I have researched ways to help him not freak out so much when we leave. I read that giving him something like this with some yummy frozen in it like peanut butter, apple sauce, wet food, etc. so he relates us leaving to him getting a yummy treat. He still freaks out when we leave, but not as bad because he wants the kong but also wants to remind us he doesn’t approve of us leaving, lol. It’s Kong, so obviously very high quality. It’s pretty heavy. I wish there was an in between size, this is a little too big and the smaller size isn’t big enough. So his tongue can’t quite reach the end inside. He also plays with it when it’s not filled with treats. We have a few so one can be in the freezer while he has one. Thank goodness he is a dog that doesn’t destroy stuff when we are gone, just yells at us when we are leaving. After we are gone he just pouts. But this gives him something to do and keeps him busy. It takes him quite a while to finish what’s inside.
