About Kong


Kong is one of the most well-known brands in the dog industry. Their classic Kong toy has taken the dog world by storm, proving to be one of the most durable, fun, and long-lasting toys on the market for tough chewers. If your dog manages to destroy everything you put in front of them, it’s time to turn to Kong. 

Kong was founded by Joe Markham, who had a heavy chewer himself. He struggled to find any dog toy that could hold up to his tough chewing. He actually found the solution to his dog’s needs while working on his car. His pup got a hold of a piece of rubber from a tire and his dog was no match for the durable rubber. Joe took this idea and created unique rubber products. He produced a quality, safe, rubber that was virtually indestructible for his pooch. 

Blue Kong

Kong has three types of rubber right now. Classic Red, Blue, and Black. The blue is a brand new version that’s 25% stronger than the classic red Kong. However, you won’t find it on their website and you won’t find it in stores. Why? The Blue Kong is supposed to be exclusively used for veterinarians and other canine groups. It’s also used by K-9 teams, drug enforcement canines, and other working pups! It helps to relieve the boredom, stress, and anxiety caused by vet visits and operations. Nevertheless, you can get this exclusive, new toy for your dog on Amazon! Use the link below to spoil your heavy chewer. 

Made with puncture-resistant, radiopaque rubber, this special rubber formula is a fantastic way to distract your pup and keep them playing longer. It can be stretched up to 9 times its original size, making it a dog-favorite. 

Additionally, the Blue Kong contains barium, a safe ingredient that will show up on X-rays. So, if your dog happens to swallow a bit of the Kong, your vet can easily see what’s going on and locate the piece instantly. 

The rubber used for the Blue Kongs are nonabrasive, non-toxic, and won’t splinter. There is no need to worry about sharp edges, toxic chemicals, or other harmful qualities. Of course, when your dog starts to rip through it, make sure to take it away from them. No matter how safe a toy is, they can still pose choking hazards if your dog rips them apart. 

Who Is This Right For?

Not sure which Kong to purchase for Fido? Well, you’re in luck- we’re here to help! The classic Kong (red) is ideal for light to moderate chewers.

Fortunately, this Kong is available in a variety of sizes to suit any pup. The small size is 1.8 x 3.5 x 6 inches. The large is 7 x 5 x 2.5 inches, and the XL is 9 x 5.5 x 3.5 inches. All sizes are made with the same durable rubber that your pooch will love to chew on! You know your pup better than anyone else. If your dog is an extreme chewer, you might want to get them one of the larger sizes. As a reminder, chew toys should be at least two inches wider than your dog’s mouth can open. This prevents them from accidentally swallowing and choking on the toy whole. 

How To Play

The Kong Blue is so much more than a chew toy! It has a classic Kong shape, meaning it has fun ridges and a hollow inside. The unique shape and fun ridges make it great for your dog’s dental health. They can chew away at it while simultaneously cleaning plaque and tartar from their teeth. 

Additionally, the core of this Kong is completely hollow. You can stuff the Kong with your dog’s kibble, treats, or peanut butter! They’ll have a blast trying to lick the treats out, and the outside of the Kong will be able to withstand their motivated chewing. 

As you can probably guess, this toy is also bouncy because of its unique rubber makeup. You can throw it around the house or outdoors for Fido. The unique shape will give your dog an unpredictable bounce pattern, captivating their attention. 


The Blue Kong is not quite as durable as the Black Kong. If your dog is a super-chewer that can destroy any toy they’re faced with, you probably want to try out the black Kong’s. They’re made with a similar material, and have an identical shape.

The only true downside to this toy is that it can pose a choking hazard if your super chewer manages to swallow pieces off of it. As always, monitor your dog’s toys and take them away if they start to crack. However, if your dog is a moderate to aggressive chewer, you probably will never have this issue with your Kong. 

Kong products are great for dogs that love to chew! The Blue Kong is one of our favorite dog chew toys. It’s durable, non-toxic, and dogs are intrigued by the shape and texture.
