The 15 Largest Dog Breeds: More Dog To Love

Some people live by the motto “bigger is better,” and it extends to their dogs too. There are many large dog breeds, each with different care and training needs.

Most large dog breeds were bred for a purpose or function. Some breeds were meant to be hunters, others guard dogs. Dogs with great endurance brought livestock or produce to market or protected the farmer’s animals. Knowing the dog’s original purpose can be very important in determining the amount of exercise a dog will need. Large dog breeds that were bred to work all day will need daily activity to work off their energy.

Living Space
Where and how you live are important factors in considering a large dog breed. City dwellers have different considerations than rural residents, and many apartment complexes, while permitting dogs, can limit their size by weight. The best dogs for people in apartments are smaller breeds such as a Boston Terriers or French Bulldogs.

While a four-pound Pomeranian can’t reach the chicken on the counter, a 100-plus pound Great Dane easily can! Without proper training, the cutest puppy can grow up into a terror. Large dog breed owners should teach their dogs good manners at home and in the community by going to a training class or taking them through the Canine Good Citizen® program.

In general, costs can grow along with a dog’s size, since many veterinary procedures, medicines and boarding are dependent on the dog’s weight. Not to mention, large dogs tend to eat quite a bit more than small dogs.
