Is there a chart for dog food protein biological value and digestibility?

Updated on September 23rd, 2025

Pet's info: Dog | Shiba Inu | Male | unneutered | 3 months and 9 days old | 7 lbs

I keep hearing about biological value and digestibility of protein sources. Is there a table or otherwise data oriented resource with this info? A table with the biological value of the most common protein ingredients in dog food?

Unfortunately there is not an easily accessible table and this is very much a grey zone. You must also take a manufacturer's claims with a grain of salt. Here are some helpful links with good information:

In my opinion, the best way to judge the quality is to examine the company who makes it. Companies that conduct research and have minimal to no issues with recalls are generally going to produce a better diet. You can also watch your dog's body. When pets produce a lot of stool or are gassy, have dull hair coats or experience frequent GI upset, these can be signs of a poor quality food.

The brand I recommend is Royal Canin. They meet all the criteria for a high quality pet food including pets producing small bowel movements with good stool quality.

I hope this helps and please feel free to post any additional questions.
