Hills Science Plan, perfect weight - great product.

by E Kelly -

Great product and price. My dog needs a good, balanced diet. The vet recommended it months ago and this is the best dry food I've come across. Haven't bothered considering another brand. Also, perhaps the most important factor, my dog loves it ! Love this website - nothing seems too much trouble so thanks again for your service.
