Buying Guide

Why should you give your dog a food that is higher in calories? What could cause your dog to lose weight? If you’re concerned about your dog’s weight, you’re not alone. Some dogs struggle to keep weight on, and we’ll outline everything you need to know below.

Why Give Dogs High Calorie Dog Food?

If your dog has something preventing them from gaining weight or keeping weight on, they may need a higher calorie food to keep them healthy. Sporting or very active breeds typically burn much more calories than older or less active breeds, and they need higher calories to make up for it. If they don’t have it, you could see them start to lose weight at an alarming rate. Foods with higher calories also support lean muscle growth, and this can help your dog bulk up.

How to Measure Your Dog’s Weight

If you’re not sure what your dog’s actual weight is supposed to be, head on over to PetMD. They have a healthy weight calculator on their website. This tool allows you to fill in all of your dog’s information before it calculates their healthy weight. You put in their age, breed, name, weight, and body condition. The calculator will give you an approximate calorie range you should feed your dog a day to reach their ideal weight. You can also consult your veterinarian if you have questions.

Another easy way to tell if your dog is underweight or overweight is to perform a quick touch and visual test. Take your hands and lightly touch along your dog’s sides to see if you can feel their ribs. You should be able to feel their ribs without pressing hard, but they shouldn’t be prominent. If you can’t, your dog is most likely overweight. If their hipbones stick out, you are dealing with a underweight dog. This short YouTube video will show you how to check your dog’s weight.

The Biggest Reasons Your Dog is Losing Weight

Did you know that there are several things that could cause your dog to lose weight? It can be scary if your dog suddenly starts to drop weight, but it doesn’t necessarily mean they’re super sick. We’ll tell you the biggest reasons dogs lose weight below.


Dogs can suffer from anxiety just like humans can. Your dog wants to feel safe when they eat. If they don’t, they may stop eating. This can result in rapid weight loss that won’t go away until you figure out what’s stressing them out and fix it. It could be separation anxiety, a switch in your routine, or maybe you invited a new baby or pet into the home. Work on treating your dog’s source of anxiety and see if they start gaining weight back. read more about anxiety in our extensive article.

Dental Problems

As your dog ages, the chances of them suffering from dental problems goes up. Their teeth can crack, break, or get cavities, and this can make it painful for them to eat. Their breath will usually start to smell very strongly as the decay advances, and you may notice their gums turn red or start to swell.

Internal Parasites

It’s very common for dogs to get infested with internal parasites like tapeworms or roundworms. If they do, they can seem hungry all of the time and eat a lot, but your dog will still keep losing weight. You could see worms in their feces as the infestation advances. Your veterinarian will diagnose and prescribe medications to treat them.

Things to Consider Before Buying a High Calorie Food

There are several essential factors that go into narrowing down the different types of dog food. The following short guide will help you.

Protein – The protein in your dog’s food should be one of the first ingredients on the label. It should come from a whole protein source like beef, chicken, or salmon.

Calorie Count – The calorie content can vary from in the mid-400s up to the mid-500s per cup. You want as many calories as possible without sacrificing quality, and this is a delicate balancing act.

No Fillers – Some dog food has a lot of fillers in it. These are empty ingredients used to bulk up the food’s formula without adding nutritional value. Instead, look for a dog food that has things like potatoes, sweet potatoes, oatmeal, and peas to round out the formula.

Grains or No Grains – Some dogs do okay with eating grains while others have allergies. Watch your dog’s coat and skin for signs of allergies and decide whether or not their food should have it.

Frequently Asked Questions

Not only will this add moisture, but it’ll also pack in more calories. You can split their large meals into smaller ones throughout the day and encourage them to eat a little more.
