The short answer: It is not recommended.
The long answer: Your dog should not eat raw eggs because they are known to contain avidin, a protein that decreases the absorption of biotin in your dog’s body. Biotin is a vitamin that converts nutrients into energy, aids in metabolising fat, and helps make your dog’s skin and coat beautiful.
Aside from avidin, raw eggs may also contain bacteria such as salmonella and E. coli, which can both affect the intestinal tract. Symptoms of salmonella include fever, lethargy, shock, vomiting, diarrhea, anorexia, weight loss, skin disease, dehydration, mucus in stool, swollen lymph nodes, abnormally fast heart rate, and abnormal vaginal discharge.
What to do if your dog accidentally eats a raw egg: Contact your veterinarian immediately, making sure to monitor your dog’s reaction to the raw egg. Go to your vet or to the emergency clinic immediately if he displays signs of food poisoning: vomiting, diarrhea, reduced appetite, lethargy, dehydration, lack of coordination, tremors, and, in severe cases, seizures and collapse.
In summary: Raw eggs do not provide significant health benefits to your dog and may cause significant illness if they are not handled properly. If you want to increase your dog’s protein intake, serve him unflavoured cooked eggs instead. These will provide him with iron, amino acids, and fatty acids that are good for his body.
