Dog breed sizes: finding the right fit
When it comes to identifying your ideal dog, choosing the right breed size is a fundamental factor.
Whether you're considering an extra-small Pomeranian, a large Afghan Hound, or an extra-large Great Dane, size matters when it comes to dogs. From their general health and life expectancy to energy levels and temperament, sizing up the right breed is crucial as you choose your future canine companion.
Welcoming a dog into your life brings immeasurable joy, but it also entails significant responsibilities. Each dog breed is unique, yet common care practices—including regular exercise, the right nutrition and mental stimulation—will help ensure their well-being.
Remember, choosing your dog is a two-way street, where their needs have to match yours and vice versa.
Sizing up your future companion
Dogs are commonly classified into size categories based on their height and weight. Here, we give an overview of the different dog breed sizes, as well as some of the characteristics, including all-important health considerations, that will help you identify your ideal dog.
What is considered a ‘large dog’?
What makes your dog a ‘large dog’? Well, their size for starters. There are some general rules for the breed category.
Weight
On average, large dogs weigh between 25 kg and 44 kg (55-97 lbs) and giant dog breeds weigh 45 kg or more (99 lbs or more)
Good to know
Despite their size, large dogs can be playful and affectionate companions.
They are often patient, tolerant, and gentle, making them perfect playmates for kids, although it’s best to supervise any dog when with small children.
Many bigger or giant dogs have high energy levels and require regular and sometimes vigorous physical activity. They can make great companions for jogging and hiking. Just make sure you can keep up with them!
Because of their weight and additional stress on their joints, larger breeds can be generally more prone to orthopaedic issues such as dysplasia and osteoarthritis.
Proper nutrition, exercise and preventive care are important for maintaining joint health in larger dogs.
Many believe that large and very large dog breeds are fiercely loyal and protective of their owners, and excellent family guardians. This can absolutely be true. However, all dogs have their own character, no matter their size or breed—and that includes large dogs who will not guard your home.
