A complete list of supplies for a new dog owner?

I would add grooming spray, pet wipes and spare Id tags to the list as well as a book on training and your dogs specific breed. From experience, I have learned that it is also important to research different pet foods to determine which is the best one for them in terms of nutrients and quality of ingredients (I feed my dogs Nutro, you can look into it if you would like more info by clicking the link) . You would also benefit from researching vets in your area to choose one that will care for your pet the best. I hope this helps! good luck with your new pet
