So, to start off I have 2 dogs. Completely opposite in size and personality. My baby loves playing with toys, while the bigger one is content looking out of the window. I got Roxy her first kong not even thinking she would like it. I was just looking for something that wouldn't get demolished in a matter of 5 minutes. It has a hole in the center where you can put a treat in it and it makes them concentrate on the treat rather than ripping it to shreds.
The Kong actually has there own brand of treats and flavorful additions that you can purchase. I have the liver flavored snaps that go into the middle (which she loves) and I also have the peanut butter in a can. It looks like cheese whiz, but also she loves it.
Now that I have bought all the product, I realize that they are keepers for me. Sometimes when I run out or don't make it to the store in time. I use her regular treats and normal, human peanut butter. I don't think she cares either way.
If you get a chance to try the Kong, I think that would be the best idea you had all day!
