Skip To

If you’ve ever given your pup a stuffed Kong, you know what an amazing treat it is for them. Kongs are versatile rubber toys made for dogs of all ages and sizes. They can be used for chewing, for playing games of fetch, and most commonly, as treat dispensers. You can purchase premade Kong stuffing online or from your local pet store, but have you ever tried making your own? If you’re wondering what to put in a Kong (besides the standard peanut butter), we’ve come up with some healthy Kong recipes that are easy to make, and that your pet will love. 

Stuffed Kong Benefits

Kongs are one of the most popular pet toys and provide several benefits to your pup besides just keeping them busy. “Kongs are mentally and physically stimulating and offer teething pups an acceptable toy to chew,” says Dr. Dawn Filos, a small animal veterinarian for more than 30 years. “I love that they learn to entertain themselves, which is especially helpful to dogs that have separation anxiety.” Stuffed Kongs can also slow down their mealtime, and “while not a substitute for brushing teeth, can help prevent periodontal disease,” adds Filos. You can also use a stuffed Kong to sneak healthy foods or supplements into your pet’s diet.

Kong Stuffing Tips and Tricks

Even if you’re not an expert in the kitchen, making your own Kong recipes for dogs can be a fun activity for the whole family. Here are a few dos and don’ts to help you with your DIY Kong stuffing:

Do select the right size and color

“Make sure to choose the correct size and color Kong for your pet. Each color represents a different toughness or purpose,” says Dr. Lindsey Wendt, an L.A.-based holistic veterinarian. “For example, the pink and blue Kongs are intended for puppies or gentle chewers. The red Kongs are the most common, and the black Kongs are the extreme version made for very aggressive chewers. Purple is for senior dogs and is a bit softer than the red but firmer than the pink and blue puppy versions.” As for the Kong size, there is a helpful chart on the Kong website.

Do monitor your dog

Most likely your pup will go nuts when you break out the stuffed Kong. Just be sure to keep an eye on your dog for possible choking, especially in the first few minutes of introducing the new tasty toy. 

Don’t use Kong treats as a meal substitute

Stuffed Kongs are a great way to keep a dog entertained but should not replace a meal. In general, treats shouldn’t exceed 10 percent of a dog’s daily caloric intake.

Don’t forget to clean

To avoid bacteria, be sure to thoroughly clean the Kong between each use with dish soap and warm water. Kong also has several cleaning tips listed on their website.
