Here's why:
* Lactose Intolerance: Puppies are often lactose intolerant. Cow's milk, including dry milk, contains lactose, which can cause digestive upset, diarrhea, and even vomiting.
* Nutritional Deficiency: Puppy formula is specifically designed to meet the nutritional needs of growing puppies. Dry milk lacks the essential vitamins, minerals, and fatty acids that puppies need for healthy growth and development.
* Calcium to Phosphorus Ratio: Cow's milk, including dry milk, has an imbalance of calcium and phosphorus, which can lead to skeletal problems in puppies.
What to give puppies instead:
* Puppy Formula: This is the best option for puppies that are not nursing from their mother. It's specifically formulated to meet their nutritional needs.
* Goat's Milk: Some puppies tolerate goat's milk better than cow's milk, but it's still not as nutritionally complete as puppy formula.
Always consult with your veterinarian before feeding any new foods to your puppy. They can provide personalized advice based on your puppy's age, breed, and health condition.
