How to Stuff a KONG for Your Dog: Recipes, Tips, and Freezing Guide

The Art of Stuffing a KONG

A KONG is only as good as what's inside it. The right stuffing keeps your dog engaged for longer, makes the KONG more rewarding, and can even turn it into a nutritious meal supplement. Here's everything you need to know about stuffing a KONG — from basic methods to creative recipes and freezing techniques.

The Basic Stuffing Method

1. Plug the small hole: Push a small piece of treat, a bit of peanut butter, or a piece of banana into the small hole at the top of the KONG to prevent food from falling out immediately
2. Fill with the main ingredient: Pack in kibble, wet food, or a mix of ingredients (see recipes below)
3. Seal the large opening: Spread peanut butter, cream cheese, or a KONG stuffing product across the large opening to seal everything in and give your dog a rewarding first lick
4. Serve immediately or freeze: Room temperature KONGs are great for quick enrichment; frozen KONGs last much longer

KONG Stuffing Recipes

Classic Kibble KONG

The simplest and most practical option for everyday use:

• Moisten your dog's regular kibble with a small amount of water or low-sodium broth
• Pack tightly into the KONG
• Seal with a thin layer of xylitol-free peanut butter
• Freeze for 2+ hours for maximum engagement

This turns your dog's regular meal into a 15–30 minute enrichment activity with zero extra calories.

Peanut Butter & Banana KONG

• Mash half a banana with a tablespoon of xylitol-free peanut butter
• Mix in a handful of kibble
• Pack into KONG and freeze

Dogs love this combination — the banana adds natural sweetness and potassium, and the peanut butter provides fat and protein.

Wet Food KONG

• Spoon wet dog food directly into the KONG
• Seal with a small amount of peanut butter
• Freeze until solid (at least 3–4 hours)

Wet food freezes into a solid block that takes dogs a long time to work through — ideal for extended crate time or separation anxiety management.

Yogurt & Berry KONG

• Mix plain unsweetened yogurt with a few blueberries or strawberry pieces
• Pour into KONG and freeze

Plain yogurt provides probiotics for gut health. Blueberries are high in antioxidants. This is a refreshing summer treat that's also nutritious.

Layered KONG (Advanced)

For maximum engagement, layer different ingredients:

1. Plug small hole with peanut butter
2. Add a layer of kibble
3. Add a layer of wet food or mashed banana
4. Add another layer of kibble
5. Seal with peanut butter
6. Freeze overnight

The layers create different textures and flavors as your dog works through the KONG, keeping them engaged longer.

Using KONG Stuffing Products

KONG makes dedicated stuffing products that make the process even easier. The KONG Treat Spiral Stick Dog Stuffing Toy is designed to be inserted into the KONG, providing a built-in stuffing solution that's easy to use and highly palatable for dogs. It's a convenient option when you want to stuff a KONG quickly without preparing ingredients.

For the KONG itself, the KONG Classic Stuffable Dog Toy for Medium Dogs is the standard choice — durable natural rubber, dishwasher-safe, and available in sizes for every breed.

Freezing Tips

• Freeze time: Minimum 2 hours for a partially frozen KONG; overnight for fully frozen
• Batch prep: Make 3–5 KONGs at once and store in a zip-lock bag in the freezer. Pull one out as needed — always have one ready.
• Thawing: Frozen KONGs can be given directly from the freezer. They'll thaw as your dog works on them.
• Mess management: Give frozen KONGs on a washable mat or in your dog's crate to contain drips

Foods to Avoid in KONG Stuffing

• ❌ Peanut butter with xylitol (toxic to dogs — always check the label)
• ❌ Grapes or raisins (toxic)
• ❌ Onions or garlic (toxic)
• ❌ Chocolate (toxic)
• ❌ Macadamia nuts (toxic)
• ❌ Avocado (toxic)
• ❌ Excessive salt or seasoned foods

Calorie Awareness

KONG stuffing adds calories to your dog's diet. If you're using a KONG as a meal replacement (stuffed with their regular kibble), no adjustment is needed. If you're adding KONG stuffing on top of regular meals, reduce the main meal accordingly to avoid overfeeding. Use a measuring scoop to keep portions accurate.

Final Thoughts

Stuffing a KONG well is a skill that pays dividends in your dog's enrichment, behavior, and happiness. Start with the basic kibble method, experiment with recipes your dog loves, and always freeze for maximum engagement. Batch prep on weekends so you always have a frozen KONG ready — it's one of the best tools in any dog owner's toolkit.
