Is this enough for my dog?

i think that's a lot already. just loving your pet is enough. playing with him, and treating him as of that of a best friend. it should be enough. ^^

All of the dogs that I've had have liked to chew on the rawhide chews. Also there are some specially prepared pigs' ears, snouts, etc. that they have liked. My current dog can chew up a small rawhide chewy in a day so I try to get him the larger ones. He also has 'flip chips' that are small-to-large squares of treated rawhide.
