How Much Weight Should a Pregnant Dog Gain
October 12, 2022
A pregnant dog should not gain or lose weight in the first five weeks of her pregnancy. Having a scale in the kennel and weighing her once a week is the best way to assure you are providing the proper amount of dog food.
What Week Do Pregnant Dogs Gain Weight?
During the last three weeks of her pregnancy, she should gain weight – the amount will depend on her breed, structure, and litter size. There is not a hard and fast rule for weight gain. The average dog will have a successful pregnancy if you increase her food intake by 10% a week from week five to delivery. She should typically gain 15 to 25% of her body weight during the last three weeks of the canine pregnancy, more if she started off too thin or has a larger than average litter.
However, the average size Golden Retriever type dog should gain about two pounds per puppy, scaling up or down for different breed sizes. Putting your hands on her at least once a week will allow you to adjust her feeding amounts and type of food to allow for ideal weight gain.
Many female dogs do not eat well around the 3rd to 5th week of pregnancy due to hormonal changes. They then usually eat very well till the last few days before whelping. A day or two before she goes into labor, she again may have a decline in her food intake. This occurs in part because of having less stomach capacity and more stomach acid related to the uterine pressure on her stomach and intestinal tract. Feeding small frequent meals can improve her ability to take in enough calories to allow for optimal fetal growth and development.
What Do I Do If My Pregnant Dog Won’t Eat?
Can pregnancy cause a dog not to eat? The answer is yes. For dogs pregnant dogs not eating as well as needed to gain the required weight, you can try these four tips:
- Feed small frequent meals.
- Top her food with Royal Canin® Starter Mousse or other food topper to entice her to eat.
- Add Breeder’s Edge® B Strong™ to her diet, even during pregnancy. The B vitamins will help stimulate her appetite.
- Give Famotidine (over the counter) tablets to reduce stomach acid. The dose is 1 tablet per 100 pounds twice a day, scaling down for smaller dogs. You can purchase this without a prescription and it is safe during pregnancy and lactation.
Pregnant Dog Body Condition Score
Your breeding female should ideally be at a canine body condition score (BCS) of 4, 5 or 6 on a scale of 1 to 9. A score of 3 or lower means she is underweight and won’t be likely to conceive and carry a nice size litter of puppies to term due to inadequate nutrition. A score of 7 to 9, means she is overweight and is more likely to have complications during whelping. Studies show that female dog obesity causes inflammatory changes in her uterus, making it less likely she will exhibit optimal fertility.
To determine the dog body condition score, touch the dog along the rib cage. Short-coated breeds can be evaluated visually. Long coated breeds should have their BCS evaluated by feeling along the ribs and backbone before breeding. The amount and type of dog food should be adjusted several months before breeding.
Can You Overfeed a Nursing Dog?
It is nearly impossible to overfeed a nursing female with a large litter. Of course, if she is looking too round or at weaning, you need to start restricting her daily food intake.
