When we adopted Drake we got him:
Blue buckle collar with matching harness (too small for him now) and leash, grooming brush, nail clippers, tooth brush & tooth paste, ear cleaning and drying solution, dog biscuits, 1 squeeky duck (his favorite till this very day), kong, bag of small raw hide bones, puppy food for large breeds, food & water bowl, carpet cleaner, stain and odor remover, and doggy bed.

I wanted to make sure that we were prepared for everything!
