A very common issue dog breeders face is having underweight or malnourished dogs. Obviously, it is never the consequence desired but it happens and there are ways to put weight on your dog fast. Some are healthy and detailed here, some have to be avoided.

In this article, we’re listing the causes breeders face that trigger a severe weight loss, but also give you the solution to make sure your dog’s body gets back to a healthy shape. Finally, we’ve thrown a great infographic to visually gauge how underweight your dog is.

Common Causes for Underweight Dogs

Here are the 6 most common reasons for weight loss in breeding dogs and puppies.

Pregnant Females


Growing pups takes away plenty of nutrients from pregnant dams. Without an increase in calories, weight loss is unavoidable.

During the first two trimesters, it’s essential that your dog doesn’t lose weight. It is equally important that your dog does not become overweight or obese during the first and second trimester. Decrease or increase their calorie intake on an as-needed basis during this time.

During the third trimester, the dam’s nutritional requirements are the greatest. The dam’s weight should increase by 15-20% during this time. This will ensure that she maintains an optional body weight after giving birth.

During pregnancy, it’s difficult for the dam to consume large amounts of food since there is limited space. High-calorie liquid supplements like Miracle Vet are the ideal solution.

Nursing Females

Due to the demand for lactation, nursing mothers require even more nutrients than growing dogs. This is the time when nutritional deficiencies are most likely to occur. It’s vital that they consume a significantly higher number of calories during this time.

Breeding Studs

During breeding, it’s common for male dogs to become fixated on the female and stop eating completely. An easy solution is adding Miracle Vet to their water. It will provide them with the energy and calories needed during breeding and prevent them from losing excessive amounts of weight.

Pregnancy and nursing bitches are feeding an entire family, not just themselves. Unfortunately, they tend to lose appetite due to tiredness, so make sure they are fed enough.


Dogs recovering from an illness such as parvo, adenovirus, leptospirosis, and distemper will all experience some level of weight loss.

Worm Parasites

Nearly every dog has contracted a worm parasite at some point in its life. These include hookworm, roundworm, tapeworm, and whipworm. The most common cause is from the mother passing roundworms to the pup while they’re still in her body. Roundworms can also develop in a puppy after birth when the pups drink worm larvae (young worms) in the mother’s milk.

Overly Active Dogs

Any dog that is overly active and burning off more calories than they’re consuming will experience weight loss. This can be easily prevented or resolved by increasing their calorie intake.

  1. Add more meat to your dog’s diet
  2. Increase its food intake and its feeding frequency
  3. Provide healthy treats

Make sure to ask your vets for some advice before changing or adding anything to your dog’s diet to prevent unwanted illnesses and to prevent having an overweight dog in return.

Health Issues in an Underweight Dog

Being underweight can pose serious dangers to your dog’s health. Similar to being overweight, being underweight is not a good thing in dogs as well. Underweight dogs can experience muscle loss and degeneration.

They can also have a weaker immune system since they can be suffering from nutrient deficiency. Additionally, an underweight dog can also experience delayed wound healing.

Their physical and mental growth can also be stunted due to a lack of important nutrients. Some dogs may experience hormonal imbalances, skin conditions, and weakened bones.

    First take very good care of the bitch, before you start your breeding programs. Mal nusished then work getting the female in good shape, then make sure the vet checks her, all this is before breeding the female. And I could write more but it will take time to. Thank you!
