Originally bred as a working dog for hunting and guarding, the Boxer has undergone a transformation in appearance and temperament over the last 100 years. Their strong, muscular build and energetic personality have made them ideal companions for families. However, their physical traits have become more exaggerated, with larger, stockier frames and a more prominent chest. This has led to some health issues, such as hip dysplasia and heart problems.

The Dachshund was originally bred for hunting small game, specifically badgers, with their long bodies and short legs designed to fit into burrows. Over the years, the Dachshund’s appearance has been exaggerated, with some breeders focusing on their distinctive long ears and unique proportions. While these traits are still charming, modern Dachshunds are more prone to back issues due to their elongated spine. This makes them susceptible to conditions like intervertebral disc disease (IVDD), especially if overfed or improperly exercised. Despite the health concerns, their curious and playful nature makes them a beloved pet.

While their strong build and terrier personality are still intact, these dogs have become more sociable and affectionate. However, the breed’s strong prey drive and stubborn nature still require consistent training and socialization to ensure they make good family pets.

Over time, their long bodies and distinctive appearance have been emphasized by breeders, leading to the exaggerated, low-slung look we recognize today. While this has made them one of the most endearing breeds, their unique physique can cause health problems, especially with their joints and ears. Additionally, their strong sense of smell still makes them great tracking dogs, although they can be stubborn and independent, making training a challenge.

Known for their grace and agility, the Saluki has remained relatively unchanged over the past 100 years compared to some other breeds.

However, breeding has led to a somewhat more refined appearance, with longer legs and a thinner, more elegant body. Their temperament is still gentle and reserved, making them excellent companions for those who enjoy an independent and calm dog. Salukis are generally healthy, though they are prone to some genetic conditions like hip dysplasia.

9. Chow Chow

The Chow Chow’s distinct lion-like mane and blue-black tongue have made it one of the most recognizable dog breeds. Originally bred in China for guarding and hunting, Chow Chows have been selectively bred for their appearance, leading to a more aloof temperament. While their independent and somewhat standoffish nature makes them excellent guard dogs, they are also known to be fiercely loyal to their families. Over the past 100 years, their physical traits have been exaggerated, with a more prominent mane and a stockier frame. This breed is prone to some health conditions like hip dysplasia and entropion, a condition where the eyelids roll inward.
