If you’ve been wondering how to put weight on your dog or how to help your dog gain weight naturally, you’re definitely not alone.

Many dog parents notice their pup looking a little too lean and want to support healthy weight gain in a safe, gentle way.

Whether your dog is recovering from illness, has been through surgery, is a picky eater, or is simply naturally slim, there are plenty of ways to help support healthy weight gain with nutritious, plant-based ingredients.

Why Is My Dog Underweight?

Before focusing on how to put weight on your dog, it’s important to understand why they may be underweight in the first place.

Some common reasons include:

• Low calorie intake
• Very active lifestyles or high energy levels
• Stress or anxiety
• Dental problems making eating uncomfortable
• Sensitive stomachs or digestive issues
• Picky eating habits
• Underlying health conditions

If your dog’s weight loss is sudden or severe, it’s always best to speak with your vet first to rule out any medical concerns.

Once you’ve done that, you can start supporting healthy weight gain with balanced nutrition and routine.

How To Help Your Dog Gain Weight Safely

1. Choose Nutrient-Dense Foods

Focus on high-quality foods packed with natural ingredients, healthy fats, fibre, and plant-based nutrients.

Look for foods containing ingredients like:

• Sweet potato
• Peanut butter
• Coconut
• Banana
• Oats
• Pumpkin
• Flaxseed
• Brown rice

These ingredients can help support healthy calorie intake while still being gentle on sensitive tummies.

Tip: You can boost meals naturally with dog-friendly additions like mashed sweet potato, pumpkin purée, banana, or a spoonful of xylitol-free peanut butter.

2. Feed Smaller Meals More Often

Instead of one or two large meals, try splitting food into three or four smaller meals throughout the day.

Frequent meals can help increase calorie intake gradually and may be easier for dogs with sensitive digestion.

3. Use Healthy Treats As A Supplement

Treats can be a great way to increase calories between meals, especially for picky eaters.

The key is choosing treats made with natural, nutritious ingredients rather than fillers or artificial additives.
