Kong makes reliable dog toys that are almost indestructible. I've been buying various Kong toys ever since my dog was a puppy (Kong has toys that are slightly malleable but sturdy for teething pups), and my dog's now into this Goodie Bone. 

Intended for dogs that weigh between 30 to 65 lbs, the large Goodie Bone is perfect for my Rottweiler. 

Shaped in a cute bone shape, you can insert treats on the sides. 

Peanut butter works amazingly. 

The grooves keep peanut butter or other treats in place, and it takes forever for my dog to finish licking them clean. 

This can be washed in the dishwasher as well. 

She has two because I like to have a spare in case the other one's in the dishwasher. 

I like to add this Kong Easy Treat to the Goodie Bone because it's much easier to dispense than a regular peanut butter jar. 

The Easy Treat is available in so many flavors - peanut butter, bacon and cheese, liver, and pepperoni. These are the flavors I've tried, and there may be more. I like the peanut butter one the best because it smells equally great for both me and my doggie. 

I always buy the value size as I go through this fairly quickly. 

Perfect for the Goodie Bone or any other Kong toys. 

You can even coat the Easy Treat on pills if your dog is on any kind of medication. 

Equipped with an easy-to-dispense nozzle, you can control the amount and placement of the treat easily without getting it on your hands.
