Great Danes get along well with people and enjoy socializing due to their kind and loving temperament. They are extraordinarily intelligent and energetic. They are not, however, the most playful breed and struggle with unusual daily routines. Great Danes are excellent guard dogs and are devoted to their family. Despite their enormous size, they are extremely docile and adapt well to their surroundings. They thrive in the presence of a family member versus being left alone.

Greyhounds are exceptionally bright, social, and non-aggressive. When given adequate exercise, this breed can develop into a calm, loving house pet that gets along well with other pets and children. Although they are not the best guard dogs, they will keep a vigilant lookout. They are insatiably affectionate and sociable. Additionally, both breeds are quite trainable.

Energy Levels

Due to the Great Dane’s higher energy level than the ordinary dog, they do not sleep nearly as much as the greyhound. They must walk and/or move around for at least a couple of hours each day to achieve their daily activity requirements. They do not necessitate strenuous activity. Giant dogs remain huge puppies for an extended period. When giant dogs are younger, their joints are prone to injury, making exercise extremely cautious.

Greyhounds become calm and tranquil after spending sufficient time outside. They enjoy sleeping ad will snuggle up to their owner. Despite their peaceful temperament, greyhounds can run at speeds of up to 45 miles per hour! They are widely bred for dog racing contests as a result.

Health Factors

Greyhounds live approximately 12-14 years, while Great Danes live seven to 10 years on average.


Life Expectancy

The typical lifespan of a healthy greyhound is 12-14 years, however, many live longer with proper care. The Great Dane is one of the shortest-lived domestic dog breeds, with an average lifespan of approximately seven to 10 years. This is largely due to their colossal size and the associated health problems. As a result, it is critical to schedule regular checks with your veterinarian, even though both dog breeds are generally healthy overall.

Health Problems

Great Danes are healthy for the most part, despite their shorter-than-average lifespan. However, due to its size, the Great Dane can suffer joint problems such as hip dysplasia, musculoskeletal traumas, and heart murmurs. Greyhounds are more prone to bloat, bone cancer, and cardiac problems than other dog breeds.
