Egg
卵 (tamago)
Definition
A protein-rich food that is commonly cooked plain and added to dog and cat meals, where preparation, not the egg itself, is what changes the safety considerations.
Key points
- Egg is a protein-dense food often cooked plain and added to dog and cat bowls
- Raw egg white contains avidin, which is thought to interfere with biotin absorption over time
- Eggshell is sometimes used as a calcium source, but the right amount depends on the whole diet
- Egg is treated as a topper, not a replacement for a complete diet
What is egg in pet feeding?
Egg is one of the easiest whole foods to add to a dog or cat bowl. It is protein-dense, carries a well-balanced set of amino acids, and most animals accept it readily once it is fully cooked. Whether it is served scrambled, boiled, or mixed into a meal, egg tends to be a topper rather than the base of a diet.
Where it fits in gut care
A complete commercial diet already supplies the protein a healthy dog or cat needs, so egg is generally treated as an addition on top rather than a foundation to build on. Feeding too much protein at once, egg included, can leave more of it undigested by the time it reaches the large intestine, where it becomes material for flatulence rather than being absorbed higher up.
As with any new food, egg is best introduced the way a food transition is handled: a small amount first, with a day or two to watch how stools respond before making it a habit.
How to serve it
Cook the egg fully and skip the seasoning, butter, or oil that a human breakfast would normally include. Raw egg white contains avidin, a protein thought to interfere with biotin absorption when raw whites are fed repeatedly over time, and raw eggs also carry a higher risk of bacterial contamination such as Salmonella. Cooking addresses both issues, which is why it is the more commonly recommended way to serve it.
Some owners crush the shell and use it as a home-made calcium source, most often alongside foods like chicken breast in a home-prepared diet. The right amount is not a fixed number. It depends on body size and everything else in the diet, so working it out with a veterinarian or veterinary nutritionist is the safer route rather than adding shell by guesswork. Egg is also a known allergen for some animals, so the first few servings are worth watching closely for skin or stool changes.

FAQFrequently asked questions
Can dogs eat eggs?
Fully cooked, unseasoned egg is generally considered acceptable for most dogs in small amounts. It is usually treated as a topper rather than a daily staple, since a complete diet already covers protein needs.
Can cats eat eggs?
The same general approach applies to cats: fully cooked, plain, and offered in small amounts. Some cats have food sensitivities, so a new food like egg is best introduced gradually.
Can dogs eat raw eggs?
Raw egg white contains a protein called avidin, which is thought to interfere with biotin absorption if raw whites are fed often over time. Raw eggs also carry a higher risk of bacterial contamination. Cooking removes both concerns, which is why cooked egg is the more commonly recommended choice.
Are eggshells a good calcium source for dogs?
Crushed eggshell is sometimes used as a home-made calcium source, but the right amount depends on body size and the rest of the diet, so getting it wrong is easy. If you want to add calcium this way, working out the amount with a veterinarian or a veterinary nutritionist is the safer path.
