How do I know if my dog needs to take a high-calorie supplement?

If you’ve adopted a dog with severe health conditions that have led to weight loss, you should consider supplementing their diet with a high-calorie supplement. Even if they are good eaters, it will take time for them for their bodies to accept more weight and keep it on. Most dogs will consider a high-calorie supplement a treat, so they won’t refuse it when you offer it. If your puppy isn’t putting on weight, you have a picky eater, your highly active dog needs additional daily calories, or your dog has health conditions that require more nutrition to thrive, you may also want to consider giving them a high-calorie supplement.

What is the best way to feed my dog a high-calorie supplement?

In most cases, high-calorie supplements are available in gel form. The thick paste is easy to feed your dog directly from the tube. But you can also add it to their food or put it in a syringe when feeding puppies. If your dog doesn’t respond well to the gel, there are also liquid and chewy treat options that may be more effective.
