Dog Food Pet Store Pack is a comprehensive guide for maximizing the health, vitality and lifespan of your dog, so you get to spend up to 8.3 years longer with your 'best-friend' than is possible, if you continue along with the method of care you currently use. If you follow the calorie recommendations I make, your dog is a perfect, slim and attractive weight. High fat and sugar levels in commercial food are a leading cause for obesity in dogs --- and obesity is the #1 health disorder seen by vets across the US.
