What you feed your new family member is important. We recommend Purina Pro Plan Large Breed Puppy and Adult Formula. Also I recommend that you get vet insurance for at least the first 2 years of your puppies life. In addition, we require (for hip warranty) www.nuvet.com/150962 vitamin/mineral/herb formula, and the hip and joint formula. (please write down order code 150962, you will need this to complete your online order, or if call, you will need to give it to the person on the phone. Call 800-474-7044. The order can't be completed without the order code) Research now shows that 75% of displaysia cases is linked to poor nutrition rather than the genetics. Use this food and these supplements, and you have great nutrition AND solid genetics! Spending a little extra now, can save you thousands later. Please ask if you want more information on these vitamins.
