Find Out How to Fatten Up a Dog If Your Pup is on the Skinny side

Just like humans, our canine friends’ weight also matters – it generally affects their quality of life. Thin dogs in particular tend to have a negative notation. Even though some are genetically modified that way, the rest get a bad rap for being malnourished. With that in mind, many pet owners are looking into ways of add some meat on the boney legs of their furry friends.

However, before sampling the variety of dog fattening food options, it is best to figure out the cause of your dog’s weight loss. You may begin by observing your dog’s feeding pattern and later paying a visit to the vet for further diagnosis. Nevertheless, here are some factors that might be contributing to your pooch’s skinny appearance.

Causes of weight loss in Dogs

Loss of appetite

If your dog suddenly seems less interested in feeding time, he or she might begin to lose weight. There are different reasons as to why your four-legged friend is not as enthusiastic about food as before. They might be suffering from an illness, too depressed to eat or simply not like a change of diet. Let’s examine possible reasons why your dog is underweight.

There are two kinds of loss of appetite, namely:

  • Pseudo-anorexia: Where your dog wants to feed, but can’t due to physical problem.
  • True anorexia: They have no desire to feed.

Some signs of loss of appetite include:

  • eating less food than normal
  • refusing to eat at all
  • less interested in treats and snack time
  • vomiting
  • Unable to eat even when interested.

Psychological trauma

Just like humans, psychological trauma causes lost weight in dogs. They might be too depressed or anxiety to eat. Such situations can be triggered by change of environment or routine and loss of a family member. Nevertheless, your dog won’t feed when in an uncomfortable environment, further contributing to a sudden decline in weight.


Diseases can affect your dog’s metabolism and lead to losing weight. Illnesses such as diabetes (common in senior dogs) affect the body’s insulin intake, which in turn affects the dog’s ability to store body fat. Furthermore, illnesses affecting vital organs that provides crucial nutrients to your dog’s body, such as the liver, can have major effect on your dog’s ability to gain weight. Respiratory diseases in some dogs may also affect their feeding patterns.

Poor feeding habits

If your dog has a change in his feed habits, he might experience a drop in weight. If a dog takes less calories than what the body requires, he might not gain healthy weight or may begin to shade some. Poor feeding habits may result from:

  • Being less interested in the type of dog food given
  • Fighting for food with other dogs in the pack
  • Feeding fewer times than usual
  • Receiving a low amount of food
  • Feeding on spoiled or deteriorated food
  • Being issued too many treats before meal time
  • Feeding on table leftovers instead of designated dog food
  • Recent vaccinations

Parasitical infections

A dog severely infested with parasites can experience sudden weight loss. For instance, intestinal worms such as tapeworms can deprive your dog nutrients making him become malnourished. For this reason, it is wise to deworm your dog after a couple of months.

Dental health issues

If your dog has some missing teeth or has a mouth ulcer, feeding will generally become hard contributing to his drastic loss of weight. In such cases, the veterinary needs to administer some antibiotics to clear of the irritation for feed to resume back to normal.

Hormonal imbalance

Dogs also experience hormonal imbalance due to thyroid problems. The problem manifests itself as high metabolism resulting in a drastic drop in weight. Luckily, when detected early, thyroid problems can be managed easily.


It goes without saying a pregnant dog is eating for two or more, so chances of losing weight are high especially if the diet is not increased and nutritious. It is best to take your dog to the vet to find out if your dog is truly pregnant or not. In such a case, the vet will advise you on a diet that is packed with nutritional value and is good for your expectant dog.

Indigestion due to stomach blockage

If your dog accidentally ingests something that’s non-biodegradable, he or she is likely to experience some stomach upset leading to loss of appetite. It is best to take your dog for an X-ray or ultra-scan if you are suspicious this might be the reason for his sudden loss of weight.

Once you have identified the cause of your dog’s lost weight, you can now begin to look into ways to help them meet an ideal weight and resolve any health issues of your beloved dog. Here are a few steps to take when fattening your dog.

Ways of fattening your dog


When it comes to food, dogs are pretty much the same as humans. These omnivorous creatures just like us, live on a variety of foods – meat, vegetables and grains – all summed up in one dog’s meal.

Dogs require a balanced diet packet with natures treats – vitamins, carbohydrates and proteins. Such a moderately sized meal will fuel your dog’s activities unlike an overindulgent diet that expands his or her waistline while putting your dog at risk of lifestyle diseases like diabetes.

  • Ideal weight

So, what exactly constitutes to a balanced diet for your fattening dog? Well, a dog’s diet should be based on his nutritional level and needs.
