AvatarByRobert Kemmer Care & Daily Living

When it comes to keeping your dog entertained, mentally stimulated, and happily occupied, a Kong toy is one of the best tools you can have in your pet care arsenal. These versatile, durable rubber toys are designed to be stuffed with treats or food, transforming simple playtime into an engaging challenge that dogs love. But the question many pet owners ask is: what to put in a dog’s Kong to make it both delicious and beneficial?

Choosing the right fillings for your dog’s Kong can turn an ordinary chew session into an enriching experience that supports their physical and mental well-being. Whether you’re aiming to slow down a fast eater, provide comfort during alone time, or simply reward good behavior, the options for stuffing a Kong are vast and varied. Understanding the types of ingredients and combinations that work best can help you tailor the experience to your dog’s preferences and dietary needs.

In the following sections, we’ll explore a range of creative and nutritious ideas for filling your dog’s Kong, ensuring that each treat time is as enjoyable and healthful as possible. From simple snacks to more elaborate mixtures, you’ll discover how to make the most out of this beloved canine toy.

Soft and Spreadable Fillings for Dogs’ Kongs

Soft and spreadable fillings are ideal for stuffing Kongs because they adhere well to the interior walls, providing a longer-lasting and more engaging challenge for your dog. These fillings can be easily mixed or layered to create variety and cater to your dog’s taste preferences and dietary needs.

Popular spreadable options include:

  • Peanut Butter: Choose a natural, unsweetened peanut butter free from xylitol or added sugars. It’s rich in healthy fats and protein but should be given in moderation.
  • Plain Yogurt: A good source of probiotics and calcium, plain yogurt adds moisture and a mild tangy flavor. Opt for unsweetened and unflavored varieties.
  • Cream Cheese: Offers a creamy texture and indulgent taste. Use low-fat versions for dogs with sensitive stomachs or weight concerns.
  • Pumpkin Puree: High in fiber and vitamins, canned pumpkin (pure pumpkin, not pie filling) supports digestion and adds a nutritious boost.
  • Mashed Banana: Provides natural sweetness and potassium, mashed bananas are an appealing and digestible option.

Layering these spreadable fillers with other treats or kibble inside the Kong can increase the time your dog spends working to extract the contents.

Incorporating Crunchy and Chewy Treats

Adding crunchy or chewy elements inside the Kong encourages your dog to chew and work harder to access the hidden goodies. These textures can also help clean teeth and satisfy natural chewing instincts.

Suitable crunchy or chewy items include:

  • Dry kibble or specialty dental treats
  • Small pieces of carrot or apple (without seeds)
  • Freeze-dried meat treats or jerky (ensure they are dog-safe and preservative-free)
  • Small biscuits or training treats
  • Dehydrated sweet potato slices

When combining crunchy items with soft fillers, place the softer layer first and then add crunchy treats deeper inside the Kong to extend playtime.

Frozen Treats for Extended Engagement

Freezing a stuffed Kong transforms it into a longer-lasting toy, particularly beneficial during warm weather or for dogs who enjoy a cool, soothing chew. Frozen Kongs slow down the eating process and provide additional mental stimulation.

Tips for preparing frozen Kongs:

  • Fill the Kong with a combination of wet and dry ingredients to create texture contrast.
  • Use water or low-sodium broth mixed with wet fillers to help bind ingredients.
  • Freeze for several hours or overnight.
  • For an extra challenge, seal the opening with a layer of peanut butter or yogurt before freezing.

Safe Ingredients to Avoid in Kongs

While stuffing Kongs can be a fun and enriching activity, it is crucial to avoid ingredients that are toxic or harmful to dogs. Some common unsafe foods include:

  • Chocolate
  • Grapes and raisins
  • Onions and garlic
  • Xylitol (artificial sweetener found in some peanut butters and gums)
  • Macadamia nuts
  • Raw dough or uncooked grains

Always consult your veterinarian if you are unsure about a particular food item.
