If you are going to trim your dog at home starting with a simple cut, at least at first, is probably advisable. Most professional groomers will be willing to give you advice on how to groom your dog. Also, you should probably be fairly tolerant of possible haircut "faux paws” at first while you are learning how to trim your dog. If having a perfect “do” for your dog is a necessity, a home haircut may not be the best option for you and your diva dog.
Trimming your dog at home can be a great way to save money and keep your dog from stressing at the groomers. Plus, it can be a great bonding time for you and your dog if he enjoys you grooming him. It may take a little practice to get the desired results--don't be too picky at first, remember your dog probably doesn't care if he does not look perfect. Clippers or scissors used at home should be appropriate for the job and in good condition just like at a professional groomer's. Good equipment is a must! Give it a try you might just be sold on a new way to get your dog trimmed by doing it from home.
