Our canine companions, though more likely to fatten over time, can gradually start to lose weight due to many problems such as dietary or lifestyle changes, changes in environment or stress levels, old age or poor metabolism, and illnesses.

Underweight dogs are not healthy dogs. They will be prone to illnesses and a myriad of health risks. Recently, a more serious issue we have encountered is the misperception of a dog’s actual body shape.

For example, a 2011 study found that over 40% of dog owners are misperceiving their dog’s body shape. In this study, 11% of dogs were actually underweight. This misperception can be fatal.

Though more rampant in the case of overweight or obese dogs, owners are also sometimes likely to categorize underweight dogs as “normal” without having the tools to determine the BCS (body condition score – the pet version of human BMI) correctly.

Having an underweight dog is a problem. Not knowing that your dog is underweight is an even bigger one. Let’s find out how can you determine your dog’s weight level at home.

Is My Dog Too Skinny?

Usually, a dog is too skinny or underweight if its spine, ribs, and pelvic bones are clearly visible. This means that there is little to no fat between the skin and the bones.

Barring certain special circumstances such as a dog that was recently rescued or a dog undergoing medical treatment, these bones should not be visible as clearly as if there was hardly any skin over them.

So, how to tell if a dog is underweight? A vet, checking bones, and tracking weight.

The best way to find out whether or not your dog is underweight is to go directly to a vet for a weight checkup. 

To check if your dog is overweight

If that’s not an option: 

Check the bones. If the bones are showing through clearly and it is a dog that is not suffering from anything that might be the reason behind its skinniness, then measure its weight. Find out the correct average weight for the breed and compare. Use this weight tool from PetMD to find the ideal weight for your pet's breed and age.

For example, the average weight of a German shepherd is 66-88 lbs. for a male and 48.5 to 70.5 lbs. for a female. If your adult German shepherd weighs remarkably lower than this, let’s say 40 lbs. on a male, then he is underweight.

Note that age also plays a critical role here. Younger and older dogs are more prone to vary from the average weight. Don’t use the global average weight metric to compare an old or a very young dog’s weight.

Help! My Dog Won't Gain Weight. Why?

Let’s go through all the possible reasons why your dog isn’t gaining weight.

Insufficient Diet

An insufficient diet is the #1 culprit more often than not.

  • If your dog is a picky eater then entice it with wet food toppings on the regular food.
  • Include more carbs, fats, and proteins in the diet.
  • Steer clear of cheap dog food products that are full of unnecessary ingredients and fillers.

Underfeeding

Underfeeding is a surprisingly dominant issue in modern households. If you are unable to provide sufficient nutrition and satiety to your dog, don’t be shy to ask fellow dog owners or ask for help in forums.

There are plenty of pet owners willing to help you. They will help guide you towards a better diet for your dog.

Health Condition

If the dog is not a particularly picky eater and if it’s getting sufficient food and still getting underweight then it’s time for a visit to a good vet.

  • Intestinal parasites, abdominal diseases, diabetes, teeth conditions (including broken teeth or painful gums), specific medications, cancer, pulmonary conditions, and other diseases can also cause your dog to lose weight.
  • Some health conditions will make the dog simply not eat regardless of what you provide.
  • Kidney, heart, and liver diseases are harder to spot from the surface. The dog will likely eat its fill in these cases but will lose fat deposits rapidly. Maldigestion and malabsorption can also be culprits here.

Calorie Deficit (Active or Working Dogs)

A rare reason can be a net calorie deficit. Even though a dog is eating well, it can still lose weight if it is especially active and energetic.

This happens most commonly with dogs who prefer to spend the majority of their day outdoors engaged in various activities that burn calories. This is good from a fitness point of view, but you need to increase the dog’s calorie intake in this case.

How To Increase A Dog's Appetite?

Increasing your dog’s appetite can help with weight gain goals. Have you been trying to feed your dog but it just won’t eat? Don’t worry, we have some solutions for you.

First of all, it should come without surprise that you have to try a few different options when it comes to dog food. Some foods might bring back unpleasant experiences or upset digestion. A product that works wonders for your friend’s dog isn’t guaranteed to work for yours too even if both are the same breed and age.

If your dog is not eating then it can also be an underlying medical condition – so get that checked first. If you are sure that there is no health condition and yet your dog doesn’t eat, then it can also be a picky eater.

9 Basic And Easy Tips To Enhance Your Dog's Appetite

  1. 1
    Take your dog for a walk before their mealtime.
  2. 2
    Cut down on table scraps and leftovers. Provide them with their own individual eating routine and diet and adhere to specific timings
  3. 3
    Use frozen dog toys that can hold food inside (like a Classic Kong or the Chilly Penguin). This mixes fun with eating.
  4. 4
    Make the food more palatable by warming it and adding a dog-friendly gravy, wet food, tuna juice, or chicken stock to it. Some herbs like oregano and peppermint can also sometimes stimulate appetite.
  5. 5
    Place the bowl at a comfortable height. Also try feeding directly on the floor or a mat (clean the surface first, of course). Try giving food separate from other pets.
  6. 6
    Try safe Vitamin B supplements or dog foods with high Vitamin B content.
  7. 7
    If it is a new dog, hand feeding or scattered food might be better options than placing food in a bowl. Go for a suitable dry kibble.
  8. 8
    Vets also recommend CBD to stimulate a dog’s appetite.
  9. 9
    You can top kibble with chunks of chicken, turkey, salmon, or lamb to make the food more palatable.

Genetics

The breed’s genetics also influence appetite. Breeds such as Siberian huskies will only eat until they are full to maximize the nutritional value out of their food bowl. On the other hand, Labrador retrievers will eat until they bloat, fall, and roll right out of the door.

Long story short, not all dog breeds are hearty eaters like pugs or Labradors. If you happen to have a breed that generally eats only to keep its belly full and nothing else, then you need to switch from a “more food” mentality to a “more protein/nutrition in the same quantity” mentality.

Advanced Guidelines

Here are some guidelines to follow to improve your dog’s appetite and help it eat more.

  • Breeds that generally eat less should be attuned to a high-fat, high-protein, and low-carb diet to help put on some weight. Making them eat cheap stuff might satiate their hunger but their muscles and fat deposits won’t improve.
  • Your dog can get disconcerted if you introduce a sudden change in diet. Dogs are not very demanding in terms of variety and pretty much like to eat the same favorites over and over again. Not eating new food isn’t uncommon. Pair it with their regular food and take it slow. Your dog will not reject it that way.
  • Overtreating your dog can easily backfire. Once dogs develop a high proclivity for sugary treats or snacks, they will be quick to reject the regular meal. Treats don’t help gain weight. Regular food does. Gradually reduce the number of treats you give so the dog has to resort to their regular food.
  • Boredom, stress, depression, fear, unknown environments, hostilities, and separation can often cause a loss of appetite, much like that in humans. This is a signal of their anxiety. Improve your bonding with your companion to make them feel better first.
  • An unclean feeding area can also contribute to loss of appetite in dogs. They like their feeding bowls, mats, and the general region clean. There is a little maintenance involved, sure, but it will ensure that your dog eats well. Treat them like your family and clean their feeding area and bowls frequently.
  • Distractions such as loud noises, bad odor, or other elements that cause disturbance can also affect a dog’s appetite. Make sure that eating is always a peaceful activity. Place their feeding area in a secluded region with no distractions and noises. Note that dogs have far superior smelling and tasting capabilities than humans, so they might be sensing some odor or tasting something bad even when you cannot smell/see it.

Best 4 Dog Foods For Weight Gain

Now, let’s talk about dog food products that are best for weight gain.

We have determined the following four dog foods to be the best in category (namely, for pups, for adults, for active dogs, and for senior dogs).

You simply cannot go wrong with any of these.

Notes:

1. If two numbers are mentioned such as 30/20, it means that the formula contains 30% protein and 20% fat in its overall composition. The remaining 50%, in this case, would be other ingredients.

The Nutra Pro from VICTOR Purpose is aimed at high-energy dogs of all ages and breeds.

Wellness Complete Health Senior Dry Dog...

The majority of high-calorie dog foods are meant for active young and adult dogs. These include high protein content and low fat and carbs content. This is ideal for active dogs, but for seniors not so much.

For weight gain in senior dogs who are less active, you need a higher fat and carb content in the formula. And that’s what Complete Health Senior Chicken & Barley recipe from Wellness Pet Food has.

With nearly 27% fat and 50% carbs (and only ~24% protein), this chicken and barley formula is a great natural tool for weight gain in senior and older dogs.

  • Calories: 416 kcal/cup.
  • Ingredients: The product contains 43 ingredients spread across vitamins, minerals, amino acids, etc. The main contents, however, are fiber, carbs, fat, and protein coming mainly from deboned chicken, tomatoes, carrots, ground barley, ground brown rice, rice, chicken fat, and sweet potatoes.

Where to buy: Various kibble bag sizes can be bought online from Chewy and from Amazon.

Best Vitamin For Weight Gain

You will find a ton of weight gain supplements and dog food products loaded with a bunch of vitamins. But which vitamin actually aids in weight gain in canines?

B Vitamins and Vitamin D are both important in any food bowl if you want to increase your dog’s weight. Extensively review all types of dog food products available to you and check their ingredients. The higher the B Vitamins are, the better it will be for you.

As per our research, we found Bully Max High Performance dog food to work really well to provide ample dosages of the required vitamins (check the review above).

There is no product that is formulated around vitamins. Vitamins are always just additions. Even if there is one, it is most definitely not made for weight gain. As such, our previous pick of Bully Max High Performance fits the bill.

Vitamin A deficiency can also lead to weight loss among other things according to a study by the National Research Council. That’s another vitamin you need to ensure in your dog’s diet.

Best Dog Weight Gain Supplement

Tomlyn Nutri-Cal Malt-Flavored...

The best weight gain supplement for dogs is the Nutri-Cal High-Calorie Dog Dietary Supplement. This easy-to-administer malty flavor oral gel is suitable for all ages and breeds.

Protein Rich Foods for Dogs

Protein Rich Foods: Chicken, Fish, Eggs, Beef, Seeds, Milk

Leftovers and table scraps are almost always a bad idea. That doesn’t imply that human food is not safe for dogs. In fact, many of the foods we eat are great for dogs.

Let’s look at a few human foods that fatten your dog without any side effects or digestive issues.

  • Plain, unsalted peanut butter is high in fat and simply the best food to fatten up your dog.
  • Scrambled or over-easy eggs without anything added to them (no salt, no seasoning, no oil, etc.).
  • Lean meat - either raw or cooked.
  • Cottage cheese and cheese.
  • Bread is good for calories and can also work as a treat.
  • Cooked boneless salmon.

Satin balls are another great option for increasing weight. You can make them easily.

Take ground beef, oatmeal, cereal, molasses, wheat germ, gelatin, coconut oil, and egg in a large bowl and mix well. Take a small amount of the mix and roll it to form a small ball. Repeat with the rest of the mix. Store these satin balls in the freezer for best results.
