Hill’s Science Diet vs Royal Canin comparison


There are several similarities between the two food brands. The meals are well-balanced in terms of nutrition, with plenty of vitamins and other supplements.

Some pet owners may find Royal Canin’s principal ingredient to be carbs rather than protein, making it less appealing to those who prefer their pets to eat as much animal protein as possible! The Science Diet was shown to be less expensive than Royal Canin’s formulae in a head-to-head comparison. As a result, while both products had all of the required nutrients and protein at an adequate level, only one put carbs first on its ingredients list and had a great nutritional value.

Before making any purchases, your veterinarian may want you to talk to them about this issue. Because of its greater protein and lower fat content, Royal Canin dog food was shown to be a superior option for tiny canine breeds than Wellness. The initial component in some Royal Canin formulae is a carbohydrate, not a protein. Science Diet, on the other hand, relies heavily on animal protein, such as chicken, as its principal constituent.

When it came to small-breed dry food, I was comparing two basic options, both of which had comparable protein and fat amounts. Because it has less fat and more fibre than the other brands, Royal Canin is the superior option for dogs that need to watch their weight.


In this case, Science Diet averaged $2.10/lb, whereas Royal Canin averaged $2.64/lb for a medium bag of dog food. The price per pound was the deciding factor for me because I believe the quality of the ingredients is equivalent.
