World's Largest Dog Breeds: 16 Giant Dogs (2023)

Giant dogs are some of the hardest-working and most recognizable breeds. But because many of them maintain the strong working instincts and drive they were bred for, they can be a lot to handle. Here are some things to keep in mind if you’re considering adding one to your family.


Giant dogs are giant puppies for a very long time and are slow to mature both mentally and physically. When giant dogs are young, their joints can become injured easily, so it’s important to be very cautious with exercise.


The bigger the dog, the bigger everything needs to be—including toys, bowls, and beds. While some giant dogs are happy and content living in small spaces, you do need to have enough space for the things they need. It’s also important to keep in mind that not everyone or everywhere is going to be giant-dog-friendly. Many apartments and hotels have weight limits for dogs, which giant breeds far exceed. It can also be much more challenging to find skilled and qualified care from dog sitters or walkers.


Giant dogs can be expensive to care for. When the dog is bigger, the bill usually is as well. Before adding a giant dog breed to your family, consider your budget flexibility and if you will be able to cover giant-size costs. Large breed dog food, toys, and other supplies are generally more expensive than those for smaller dogs. In addition, medication for giant dogs is going to be more expensive. Unfortunately, not all vet clinics—especially those in urban areas—will be equipped to safely handle giant breeds and you may need to shop around or travel to a vet who can accommodate a giant dog for X-rays, surgery, etc.


Regardless of size, all dogs need training, but it’s especially essential for giant breeds. Misbehaviors that people might think are “cute” when they happen with small dogs—like jumping up, counter surfing, and pulling—aren’t so adorable when your dog is a giant. These are dogs who will outweigh many people when fully grown, so it’s important to begin training giant dogs as very young puppies. Training should always be fun and positive. If you’re considering adding one of these giants to your life, look at theS.T.A.R. Puppy Programto get training off on the right foot.

If you’re okay with all of these potential challenges and you still think bigger is better when it comes to dogs, one of these breeds might be the right fit for your family.
