I have a female that doesn't produce enough milk for 10 puppies. They are almost 4 weeks old and they are getting 5 ounces, 2 times daily of the recipe of 10oz Goat milk, 1 cup Plain regular fat yogurt, 1 egg yolk and 1 tbsp Karo syrup. They are eating softened puppy food for two meals. I'm wondering when I can quit the supplement milk. They don't seem to be drinking water although it is available to them. I'm afraid in this heat they will get dehydrated if I don't supplement. They also will eat puppy food right out of the bin. Any suggestions on when I can quit the supplement.
