"I used several different dog foods until finally at a Vet's office in the Azores Islands off the coast of Portugal said my puppy of 7 months was weigh overweight at 14kg 800 grams. She put him on the Hills Science Diet and in two months he weighed 11kg, 100 gramss a lost of about 8 poiunds. For a small Scottish Terrier this is an amazing loss of weight. He seems healthier, more energectic, loves the food and does not seem to overeat with this food even though there is still food in the bowl when I feed him."
