Goat’s milk is highly nutritious, containing protein, fatty acids, vitamins, minerals, and trace elements. In addition, goat’s milk is slightly higher in calcium, potassium, niacin, and vitamin A than cow’s milk. The fat globules in raw goat’s milk are smaller than those in raw cow’s milk, making the milk more easily digested.
Most dogs don’t tolerate cow’s milk well at all, developing gastrointestinal problems that can include vomiting, diarrhea, gas, bloating. and other issues. This is why most experts don’t recommend adding milk to a dog’s diet, whether puppies or adult dogs.
But for many dogs, goat’s milk doesn’t cause the same problems—and in fact, can act as a nutritional supplement, especially to a home-cooked or raw food diet. In addition, many dog breeders will offer nursing puppies a formula based on goat’s milk rather than cow’s milk.
