Before ultrasound – She will be on Science Diet Maintenance. 1.25 or 1.5 cups twice a day. I raise her food so the pups can grow up big and strong and she usually will eat less about 10 days before her due date, so I like her to have some fat stored up on her.
After ultrasound – She will switch (in 5 day period) to Science Diet Puppy and they will increase the amount of food by about 1 cup a week.
Loss of appetite – She will loose her appetite about 2 weeks before her due date. Do all that you can to get her to eat. Try only 1 cup per meal, try canned food, dry kibble instead of wet, dog sausage log, dog biscuits, any dog food product on the store shelf. You can switch foods without having to worry about loose stools. Her nutrition is more important than a soft serve stool. I will buy 1 can of food from each dog food company (Iams, Purina, Natural Balance, etc). She will tire of a flavor after one meal, so variety is important. Sometimes she will only eat kibble, other times she will only eat canned food. Sometimes holding the bowl up off the floor helps. Sometimes going for a walk before eating. It is best to stay with dog food and not use people food.
