Does 25% protein dog food make a difference over 20% for my dog?

Updated On September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Female | spayed | 5 years and 3 months old | 17 lbs

I'm debating between picking a dog food with 20% protein or 25% protein. Since dogs are considered carnivores by some would 25% protein be better for her?

The actual laboratory level of protein is of limited value in picking a food as it must be weighed against the quality of the protein (how much will be digested /absorbed and how much will be processed as 'waste' by the liver and kidneys and how much will be excreted directly) as well as her lifestyle and any health or weight issues she may have. With any new food it is important to introduce gradually and monitor for any signs of upset stomach, weight gain or weight loss which might indicate a change in the diet or amount fed would be required.

    Thanks for using Petco Pet Education Center, formerly Petcoach! Quite frankly that small of a difference really would not make any difference. I would go with the diet that you prefer based on other factors like the price. Good luck and have a great day!
