Top 20 Largest Dog Breeds

Most dog lovers will tell you that good dogs come in all sizes.

But there is something endearing about those gigantic breeds that can not only meet you eye-to-eye, but that consider themselves cuddly lap dogs at the end of the day.

Large dog breeds are typically in the working group of dogs, which means they were originally bred to help people with tasks like pulling sleds and carts, guarding livestock and homes, and protecting families, according to the American Kennel Club.

“Breeds in the working group tend to be known for imposing stature, strength, and intelligence,” says the AKC website.

With a big dog, owners need to be prepared for everything that comes along with bringing a large breed into the family. According to the AKC, there are a few things to keep in mind with large dog breeds:

• Development: Bigger dogs tend to mature and develop slower than other breeds, both mentally and physically. That requires being extra cautious with their joint development, as they can injure themselves more easily.
• Space: Big dogs will require big things, including large beds, toys and food bowls. This also includes their living space and the space in which they can freely play.
• Expenses: Bigger dogs come with bigger bills. While their toys, food and supplies are often more expensive, keep in mind that veterinary costs for large dog breeds will also be higher due to their size. And don’t be surprised if pet insurance for your large dog costs more, as well.
• Training: Proper behavioral training is critical when it comes to big dogs because behaviors often overlooked in smaller dogs, such as jumping on people and leash pulling, can be more dangerous with a big dog. Owners will need to ensure the dog receives appropriate training from the start.

“Owning a large breed dog can be a wonderful experience as long as a potential dog owner is prepared,” says Charlotte Reed, a pet care and lifestyle expert and host of The Pet Buzz, a nationally syndicated pet talk radio show.

“It is important to note that large breed dogs continue to maintain the drive that they were bred for as well as their working instincts,” Reed adds. “As a result, they are not for all dog lovers.”

Here’s a look at the top 20 largest dog breeds (by weight) and why there’s just more to love about each one.
