Just like humans, dogs come in all shapes and sizes. While some owners struggle with overweight pets, others face the challenge of helping their furry companions gain a healthy amount of weight. Whether it’s due to a recent illness, high energy levels, poor nutrition, or a naturally fast metabolism, some dogs need extra calories to maintain optimal body condition. This leads many pet owners to ask: “What human food can I give my dog to gain weight?”
This question is both important and delicate. Feeding your dog human food should always be done with care and informed knowledge. Not all human foods are safe for dogs, and some can even be toxic. However, when chosen wisely, many human foods can offer a nutritious boost to your dog’s diet and help them gain healthy weight.
In this article, we’ll explore the causes of underweight in dogs, the right types of human foods that can be safely incorporated into their diet, feeding tips, and potential risks to watch out for. By the end, you’ll have a complete guide to safely helping your dog gain weight with human food.

Why Is My Dog Underweight?
Before jumping to the solution, it’s important to understand why your dog might be underweight. Several factors can contribute:
Cause | Description |
---|---|
High Activity Level | Active breeds like Greyhounds or Border Collies may burn more calories. |
Illness or Parasites | Conditions like worms, diabetes, or kidney disease can cause weight loss. |
Stress or Anxiety | Environmental changes can affect a dog’s appetite and metabolism. |
Poor Nutrition | Incomplete or unbalanced diets can lead to malnourishment. |
Picky Eating Habits | Some dogs are just choosy and may not eat enough. |
If your dog is losing weight rapidly or appears malnourished, a veterinarian check-up is essential before trying to fix it with food. Once medical causes are ruled out or treated, dietary changes can be safely introduced.
Signs Your Dog Needs to Gain Weight
It’s not always easy to tell if a dog is underweight. Use these signs as a general guideline:
- Ribs, spine, and bones are clearly visible
- No fat layer can be felt
- Dull coat or shedding fur
- Low energy levels or fatigue
- Loss of muscle mass
- Weighs significantly below breed average
If these signs match your dog’s current state, it’s time to consider a nutrient-rich, calorie-boosting diet, including some safe human foods.
