My Dog Loves Junk Food

I know that it's not a good thing that my dog eats junk food, but I give him one occasionally. His favorite? A small bag of Jack 'n Jill Chippy, the original flavor.

It's a treat I give him every once in a while but I know it's not really good for him because of the too much salt and artificial preservatives most junk food contain. Maybe I should just stop giving him one? Yes, that's the best thing that I should do.
