Ondergewicht bij huisdieren: oorzaken en tips

Underweight in Pets: Causes and Tips

Most of the information you can find about keeping pets at a healthy weight is written from the perspective of preventing animals from gaining weight and becoming overweight. Of course, that is very important, but what if your dog or cat is actually underweight? It makes sense that more food will help the animal gain weight, but how do you do this responsibly? In this blog, you will learn more about how to recognize underweight, the causes of underweight, and how to help your pet gain weight in a healthy way.

Causes of underweight in pets

A pet’s body uses a certain amount of energy every day. This energy comes from food in the form of fats, proteins, and carbohydrates. When the energy used equals the energy the pet takes in, the energy balance is stable and the pet’s weight remains the same. If the pet takes in more energy than it uses, it gains weight. If it takes in less energy than it uses, it will lose weight.

Below we discuss the most common causes of weight loss in pets:

  • Picky eater

Some dogs and cats eat almost anything, while others are harder to convince when it comes to food. They can be sensitive to factors such as taste, texture, and feeding times.

  • Stress or anxiety

Whether it’s thunder, fireworks, strange visitors, a new housemate, or going to the groomer, all these events can cause fear and/or stress in your pet. Stress-related weight loss is therefore definitely a possible cause of underweight in animals.

  • Illness, injury, or pain

If your pet is losing weight or losing its appetite, there may be an underlying illness or injury. Pain can also cause weight loss. If you suspect your dog or cat is unwell, visit the vet to rule out medical causes such as thyroid problems, digestive issues, or dental diseases.

  • Parasites

It is very important that a dog or cat is regularly dewormed, as parasites like worms or Giardia can cause weight loss. Parasites prevent nutrients from being properly absorbed in the body. A dog or cat may also have diarrhea, feel weak, and seem constantly hungry.

  • Too much or too little exercise

Some dogs or cats are simply very active but do not get enough nutrients to maintain their weight. On the other hand, pets that do not move much may have a reduced appetite.

  • Age

Dogs and cats tend to lose weight as they get older, for example due to changes in activity level, appetite, and illnesses.

  • Malnutrition

If your dog or cat eats its daily meals well but still loses weight, it is advisable to check whether the pet is getting enough food each day. Check the recommended daily amount on the packaging of the food the pet receives. Keep in mind that the amounts recommended on packaging are only suggestions. If you think your pet needs more food than recommended, increase the portions slightly.

Risks of underweight in pets

Although overweight is more common in pets than underweight, underweight is at least equally dangerous for an animal. If a dog or cat is too thin, muscle tissue will be broken down so the body still gets all essential proteins. The result is that the pet will have less energy and strength, increasing the risk of physical injury and/or accidents. Vital organs also do not get enough nutrients to function properly. Finally, pets with underweight have a weaker immune system, making them more susceptible to diseases.

How do you know if your pet is underweight?

For some animals, it is very clear if they are too thin, but for others it can be harder to determine if they are underweight. Especially for pets with thicker or longer fur, it can be difficult to see. The rule of thumb is that at an ideal weight, the ribs of the animal are not visible but can be easily felt. From above, you can clearly see the waist. With underweight, you can clearly see the ribs, hips, and spine. In addition, muscle mass is clearly reduced and the animal has no body fat left. Pets that are too thin often also have lower energy levels and can even be depressed. Their coat will also look duller and drier. Finally, excessive shedding is also a symptom of underweight.

If you are unsure whether your pet is too thin, consult your veterinarian.

 

How can you help your pet gain weight?

When a pet has lost a lot of weight, it is important to find out the cause of the weight loss. Sudden significant weight loss can be a sign of illness or other health problems. If this is the case, contact your veterinarian to identify or rule out any health issues.

Every pound goes through the mouth, right? It is often thought that underweight can be solved simply by feeding the animal more. Unfortunately, this is not true, and there is much more involved in responsibly helping an animal gain weight than just giving more kibble, wet food, or treats. Below we share some tips on how you can help your pet gain weight in a healthy way:

  • Choose high-quality food

To help a thin pet gain weight, it is important to choose good quality food that contains a high level of fats and proteins. These two nutrients provide energy. Carbohydrates also provide energy alongside proteins and fats, but in large amounts, they are not healthy for your dog or cat. Therefore, try to avoid food with many fillers (such as wheat, rice, potatoes, or other grains), as they contain few nutrients and can cause digestive problems in large amounts. Riverwood foods contain no grains or potatoes. Instead, we have chosen yellow peas because of their low glycemic index. These carbohydrates are broken down slowly, which is better for a healthy and stable blood sugar level.

The variants with Reindeer, Deer & Wild Boar for dogs and Duck, Reindeer & Wild Boar for cats are especially suitable for dogs and cats that need extra energy. Both variants contain a high level of balanced and high-quality proteins and fats.

  • Tasty favorites

Do you have a very picky dog or cat that has lost a lot of weight because they leave their food? Then you can choose to mix the kibble with a little wet food. The smell and texture of the wet food will likely encourage eating. When choosing wet food, opt for high-quality food with a high meat content. Riverwood's Mono Protein canned foods for dogs are based on a single protein source and consist of 70% meat. View the full range of Mono Protein canned foods for dogs here.

Would you rather not give your four-legged friend wet food? Then you can also choose a supplement as a topper over the food. The Riverwood Norwegian Salmon Oil is a dietary supplement suitable for both dogs and cats. The strong smell of the salmon oil can stimulate eating. In addition, the Norwegian Salmon Oil is also rich in unsaturated omega-3 fatty acids, which provide extra support for the skin and coat.

We have previously written blog articles with tips for picky dogs and cats. Tips for picky dogs can be found here, and in this blog, you will find tips for picky cats.

  • Feed smaller portions and spread them throughout the day

A good tip is to divide your dog or cat's meals into three or four portions per day, instead of one or two large feeding times per day. Smaller portions help the animal digest its food better and absorb the energy from the meals more effectively. It is important that no more than six hours pass between meals.

  • Give responsible snacks

Many snacks contain a lot of calories. These treats can be a good addition to your dog or cat's daily meals. However, choose healthy snacks. Healthy snacks contain natural ingredients and no added sugars or salt. Check out the range here healthy reward treats and natural chew treats for dogs from Riverwood.

  • Keep the animal active

It may sound a bit contradictory to recommend exercise for a dog or cat that needs to gain weight. Exercise actually burns calories, right? While that is true, exercise is beneficial because it helps a lean dog or cat build muscle mass. As an added bonus, increased activity will boost their appetite. Additionally, exercise is good for digestion. Make sure there is at least 30 minutes between eating and exercise.

If you want your dog or cat to be more active, keep in mind that you should increase activity gradually to prevent injuries if the animal is not used to extra exercise.

  • Weigh your pet regularly

Weighing your dog or cat weekly is a good way to monitor your pet's weight. It provides a clear picture of whether the animal has gained, lost, or maintained weight over time.

  • Keep a feeding diary

By keeping a feeding diary, you become aware of all the food your pet consumes in a day. Additionally, you can determine whether the strategy to help your four-legged friend gain weight is working or not. If the animal's weight changes at the next weighing—weight gain or loss—you can look back at the notes to see what happened.

With the above tips, you and your four-legged friend can work together to ensure they reach a healthy weight again!
