1 - Never feed kibble (dry food), if possible.  Even the best kibble in the world is inferrior to a raw or home prepared diet.  If you must feed kibble, feed a kibble high in meat-protein.  Stay away from grain-based kibble.

2 - Provide adequate exercise, play, leadership and grooming for your dog. 

3 - Do not over-vaccinate.  Vaccines are NOT REQUIRED every year. 

4 - Try to avoid chemical topicals for flea and tick prevention.  There are natural alternatives.

5 - Use stainless steel or high quality ceramic or glass eating and drinking bowls.  Plastic/PVC contains harmful toxins to your pet.  Plastic can also cause allergies or facial acne

6 - Use spring or unchlorinated water.  If you use tap water, let it sit out for 30 hours so it off-gases the chemicals and chlorine - many chemicals evaporate providing better quality water for your pet.
