Get Dogs to Gain a Healthy Weight

Helping your dog maintain a healthy weight is an important part of being a pet owner. Even healthy dogs can be underweight or overweight, but you may be particularly concerned if your dog has lost weight due to an illness or injury. After a trip to the vet to rule out underlying problems, many underweight dogs can gain weight by altering diet and lifestyle.

Steps

Diagnosing Low Weight

1. Record your dog’s weight. If you believe that your dog is underweight, you need to begin keeping track of the dog’s weight so that you can track the dog’s weight loss, and then his weight gain as you implement weight-gaining strategies. Be sure to share this information with your vet.
2. Consult a veterinarian. You need to be sure that there is nothing causing your dog’s weight loss that needs medical attention. Your dog may have an illness or parasite that isn’t immediately obvious to you that your vet will be able to determine.
   • Illnesses such as diabetes, cancer, hepatitis and inflammatory bowel disease may manifest as weight lost, but require additional treatments and medications. Therefore, a pet with an undiagnosed condition will not improve with food alone. In fact, they will get much worse without proper treatment.
3. Determine your dog’s ideal weight. Talk to your vet about using body conditioning scoring (BCS) to help objectively assess whether your pet is too thin, too heavy or just right. A sample chart can be seen here. If your dog seems underweight based on the BCS, you should talk to your vet about an approach to help your dog gain weight.
   • In general, your dog is at a healthy weight if you can see their waist, you can feel their ribs when petting their sides without actually seeing the outline of the ribs and their belly curves upward to meet their hips.
   • If you can easily see most or all of the ribs, the backbone or hip bones, your dog is likely too thin.
   • Some breeds, like Greyhounds, and some hunting and herding dogs (Border Collies, Pointers) tend to be leaner than other breeds like Mastiffs and Labrador Retrievers.
4. Deworm your pet. It is best to have your vet do a fecal test for intestinal parasites, but if you are unable to do that, you can diagnose and treat your dog for worms from home.
   • A dog that has an intestinal parasite infection may be underweight because the parasite is sapping the nutrition out of the dog’s food before the dog is able to process it.
5. Ensure that your dog is getting appropriate exercise. A dog’s weight is related to his overall health, and part of your dog’s health is getting adequate gentle exercise.
   • Make sure to consult your vet before embarking on a rigorous exercise plan. Some dogs suffer from arthritis, neurological difficulties or metabolic diseases that lead to muscle wasting which would require special treatment under the guidance of your veterinarian to improve your dog’s health without additional injury.
   • Gradually increasing controlled walks on leash is usually safe for most dogs and less likely to cause injury. Swimming is a great no impact exercise for dogs who don’t mind getting wet. Make sure the entry and exit from the water are set up to prevent injury getting in and out of the pool, lake, or river.

Adding Calories to Your Dog’s Diet

1. Add an extra meal into your dog's daily diet. If you feed your dog once a day, add a second meal. If your dog is already fed morning and evening, add a meal during the middle of the day. Do not necessarily change the diet you are already feeding, simply add one more meal to the day to add calories.
   • Keep in mind that by increasing your dog’s diet by a whole meal, you are also changing the bathroom habits of your dog, which may require altering your dog walking schedule.
2. Assess the quality of your dog food. Dog food comes in a wide variety of quality. You should be sure that the food you are feeding your dog is providing an adequate number of calories and an appropriate balance of nutrition.
   • Checking the protein and fat content of the food you currently feed is easily done by checking the information provided on the side of the bag.
   • The calories per cup will not always be found on the package, so you may have to go to the manufacturer’s website or call the manufacturer to get that information.
   • You will also find an ingredient list on the side of the bag. Look for foods that begin the ingredient list with a protein, such as “beef” or “chicken” or “lamb” instead of a carbohydrate like corn or wheat.
   • You can check the quality of ingredients of your current dog food http://www.dogfoodadvisor.com/ here.
   • Talk to your veterinarian regarding your pet’s nutritional needs including the recommended caloric intake per day for your dog. Additional information can be found at: http://vet.osu.edu/vmc/basic-calorie-calculator.
3. Supplement the dog’s food with appropriate human food. Adding some yummy, safe “human” food to your dog’s diet can help increase a dog’s enthusiasm for eating. Non-fat, no salt chicken broth, beef broth or vegetable broth is very tasty, especially if you warm it up before placing on top of the dog’s food. You can find non-fat no salt broths in the grocery store pretty inexpensively. A few tablespoons will add nice flavor to your dog’s food.
   • A few tablespoons of roasted chicken without the skin, boiled egg or plain sardines (or mackerel) will often help awaken the appetite of most dogs and are healthy sources of protein and calories.
   • Dogs can get sick if fed too much fat, so stick to protein and carbohydrates to add healthy calories to the diet.
   • Other foods to try are the water from canned tuna, non-fat cottage cheese, non-fat plain yogurt, or plain canned pumpkin.
   • Avoid human foods that can be dangerous to dogs’ health, such as chocolate, raisins, grapes, onions, garlic, and anything with mold on it.
4. Try a different kind of food. If your dog is not responding well to the food he is eating, try giving him a different (high quality) dry food, a high-quality canned (wet) food, or follow a respected homemade dog food diet. High quality pet foods generally list the first ingredient in their formulations as a protein, such as “beef” or “chicken.”
   • If you are home cooking the whole diet for a dog over a long period of time, it is extremely important that the diet is complete and balanced nutritionally. Using a reputable source from your veterinarian for your dog food recipes is recommended, and make sure that you don’t leave out any ingredients when you cook.
   • No one diet is “perfect” for every dog, so be sure to do some research with the help of your veterinarian before changing to a home-cooked only diet for your pet. A few resources to consider when starting your research are The Whole Pet Diet by Andi Brown and the Dr. Becker's Real Food for Healthy Dogs and Cats by Beth Taylor.
5. Add water to your dog’s dry food. If your dog is not enthusiastic about eating his dry food, try adding hot water to the dried food then letting it cool so that it's mushy. This often makes the food more appealing to dogs.

Warnings

• Be aware that a drastic change to a dog’s diet can cause an upset stomach. Talk to your vet about safely transitioning to a new type of food.
• If you are adding human food, such as pumpkin, to your dog’s diet and your dog has soft stools, you may need to decrease the amount of human food you’re adding to his diet.
• Do not embark on a big exercise routine with your dog if they are not used to it. Just like us they need to gently start then introduce more.
• Don't force your dog to eat, you can only tempt them.
