Raw eggs are nutrient-dense and are a great source of raw food for your Dog or Cat. We suggest adding a couple of whole eggs to your pets raw food meals each week - shells included. Eggs are a great source of protein and have a range of other beneficial nutrients in them such as Vitamin B12, Vitamin A, Iron and Riboflavin.
You may read that feeding egg whites could cause biotin deficiency. The egg white contains avidin (an enzyme) which inhibits biotin (a B vitamin); but it would take a large amount of egg white to cause a biotin deficiency, and mother nature thoughtfully put a whole lot of biotin into the yolk to balance things out.
Salmonella contamination can be an issue with raw eggs, so get yours from the best source you can (shop from locally known sources, we recommend free ranging, pasture raised chickens); and only feed raw eggs to pets that are likely to have good gastric acidity (ie healthy, raw-fed dogs and cats). Strong gastric acidity allows carnivores to ingest potentially pathogenic bacteria.
