What Are High-Calorie Supplements For Dogs?
High-calorie supplements for dogs are dietary additives that help underweight dogs to gain weight. They can also prevent dogs with certain conditions from losing weight.
They contain super-dense ingredients that are naturally high in calories to increase or maintain the dog’s weight at a steady, safe rate. High-cal supplements should also contain key nutrients that support the entire body to help it accommodate the influx in calories.
Most high-calorie supplements come in the form of tasty liquids, gels, pastes, and powders that can be either eaten off the end of a finger or mixed in with food, which is especially useful for fussy eaters.
There are also generic supplements suitable for different pets, which are ideal for animal shelters, and dog-specific supplements, which are great for owners. Some dog-specific supplements are suitable for all dogs, while others are designed for puppies or adults.
When looking for a supplement for your dog to stimulate their appetite, consider their needs, too. For example, high-fat supplements are best suited to dogs who need to gain a lot of weight. Others double up as muscle builders for large and active dogs, and some focus primarily on weight gain/maintenance during illness or illness recovery. There are even appetite builders for anxious dogs and those with added nutrients for joint support for senior dogs.
You will have to tailor your dog’s dosage according to their size via the instructions coming with the product. If your dog is severely underweight, your vet may advise that you build up their dosage gradually so as not to overwhelm their body.
Key ingredients to look out for include:
- Healthy fats from natural sources (e.g., fish oil and coconut)
- Protein from natural & high-quality sources
- Key vitamins and minerals
- Omega 3 & 6 fatty acids
- Probiotics & other digestion aids such as flaxseed and pumpkin
Things to avoid include:
- Chemicals & synthetics
- Artificial additives & preservatives
- Added sugar
- Trans fats
Other things to you may also want to consider:
- Vet-recommended or trusted brands
- Products approved by official bodies
- High ratings & good reviews
- Ethically & sustainably sourced ingredients
Pros & Cons
Although you should still (and always) feed your dog a sufficient, nourishing diet, the biggest pro of using a weight gain supplement is that it gives you peace of mind. You know that your dog is getting the number of calories they need to gain weight in one convenient product.
If you do give your dog a weight gain supplement, you must make sure you give them the recommended dosage every day and stick to it until they’re healthy. Otherwise, you could wreak havoc with their body.
Another con is that weight gain supplements, like all supplements, can also have side effects, so make sure you read about the possible side effects of the product online or in the pamphlet that comes with the product.
Dogs & Weight
Like all animals, dogs can become overweight or underweight. Their ideal weight range depends on their breed, size, and age. Your vet will tell you your dog’s ideal weight and monitor it at annual check-ups, but the American Kennel Club also has a weight chart that you can use.
Dogs can lose weight from illness and stress. Metabolic disorders such as diabetes, cancer, diseases involving the major organs, such as liver disease, parasites, gastrointestinal conditions, dental diseases, maldigestion disorders, and malabsorptive disorders can all cause dramatic weight loss and prevent weight gain.
When there is no apparent cause for weight loss, owners should look for other unusual physical symptoms such as changes in the coat and ask their vet for an examination.
Stress can also cause dogs to lose their appetite and therefore lose weight. Other symptoms of stress include panting, pacing, and destructive behavior. Common causes of stress include separation anxiety, boredom, being underexercised, phobias, trauma, life changes, and illness or death in the family.
A good way to tell if a dog is severely underweight is if its ribs and lumbar vertebrae are easily felt and visible, and its waist and pelvic bones are prominent.
One of the most common reasons dogs become underweight is malnourishment from starvation. Malnourishment often occurs in rescue dogs and is usually a result of abuse or neglect, but it can also be due to homelessness.
Preventing Weight Loss & Gaining Weight
When a dog is underweight, vets often prescribe a special diet of high-calorie, high-protein, high-fat, nutrient-rich food to help them gain weight. This food should be given on a regular feeding schedule, which may include slightly smaller but more frequent meals than usual. Light dog exercise is usually suggested to increase appetite, and for those that need a little extra help, vets may recommend using a weight gain supplement as well.
If a dog is at risk of becoming underweight, vets may suggest a special diet, using a supplement, or both, depending on the situation.
If your dog’s weight loss has an underlying cause such as illness or stress, you should address the underlying issue first. Once your vet has diagnosed your dog, you can start to treat or manage their condition and focus on gaining back the weight. If your dog is experiencing stress and you cannot eliminate the cause, try to do some positive association training or invest in some anti-anxiety products. A fixed routine, lots of interaction, affection, exercise, play, and mental stimulation will also help too.
High-Calorie Supplements For Dogs: FAQ
Dogs can lose weight from illness and stress. If you’ve noticed a dramatic change in your dog’s weight that you can’t identify the cause of, make an appointment with your vet as soon as possible.
Metabolic disorders such as hyperthyroidism, cancer, diseases involving the major organs, such as kidney disease, parasites, gastrointestinal conditions, dental diseases, maldigestion disorders, and malabsorptive disorders can all cause sudden or dramatic weight loss. Stress can also cause dogs to lose weight from a lack of appetite.
If you have tried familiar favorites and new, exciting foods, talk to your vet about Entyce. Entyce is a prescription oral solution for dogs that contains the chemical capromorelin, a strong appetite stimulant.
High-calorie diets and/or weight gain supplements are typically prescribed or recommended to dogs who need to gain weight. Food should be given on a regular feeding schedule and light exercise is also often suggested to increase the dog’s appetite. A vet should always oversee significant dietary changes and the implementation of supplements.
If you’re feeding your dog more food and they are not gaining any weight, you’re either not feeding them enough, or there is an underlying medical issue going on. Either way, you should contact your vet and let them get to the bottom of it.
Your vet will tell you your dog’s ideal weight and monitor it at annual check-ups, but the AKC also has a weight chart that you can use online. A severely underweight dog has a prominent waist, as well as ribs, lumbar vertebrae, and pelvic bones that are very visible and easily felt.
Dogs will lose weight naturally as they age, and their muscles begin to waste away, especially if they have arthritis. However, it shouldn’t be significant enough to make them underweight, and you should be adjusting their diet, medication, and exercise as per your vet’s advice.
There are several types of weight gain supplements for dogs. Which one is best for you depends on your dog’s needs and personality. For example, powders and liquids that can be mixed into food may be better than pastes and gels for fussy eaters.
You should also consider the ingredients of a supplement. Weight gain supplements with especially high-fat content are well suited to malnourished and seriously underweight dogs. Those with added electrolytes and probiotics are great for dogs recovering from illness, and high-protein supplements are ideal for active dogs. There are also appetite enhancers for stressed dogs and some even have added nutrients for older dogs.
Those are our top ten high-calorie supplements for dogs. If your dog needs to gain or maintain weight, try out one of our recommendations & always consult your vet first.
