Why These 10 Dog Breeds Are Used More Than Others In Labs

Most people picture mice in labs, but dogs have also been part of scientific research for years. Some breeds are more commonly used than others, often selected for specific studies. Their role in research has contributed to medical advancements while also sparking discussions about their place in laboratories. If you want to know which ones are affected and why, keep reading to find out.

Beagles

Beagles have long been the unfortunate poster dogs of animal testing. Their even temper and adaptability make them ideal for research. A 2004 report showed that 97.3% of dogs used in experiments were beagles. Their trusting nature makes them easy to handle in labs. 

German Shepherds

German Shepherds are well-known for their intelligence, making them invaluable to law enforcement and search teams. However, researchers also study them for the same reason. Their genetic predisposition to hip dysplasia and degenerative myelopathy makes them a key focus in neurology and muscular disorder research, as these conditions closely resemble those found in humans.

Labrador Retrievers

Friendly and highly trainable, Labradors end up in research facilities more often than people realize. They are frequently used in nutrition and orthopedic studies due to their genetic predisposition to obesity and joint issues. Labs trust humans completely, which makes their use in experiments particularly tragic for those who care about animal welfare.

Golden Retrievers

Golden Retrievers are well-known for their affectionate nature, but that same trait makes them easy subjects for lab research. Studies on inherited diseases often involve this breed. Goldens have one of the highest rates of canine cancer, which unfortunately makes them valuable for medical research on potential treatments.

Hounds (Mixed Breeds)

Not all dogs used in labs come from a single breed. Mixed-breed hounds are chosen for studies requiring genetic diversity. Their backgrounds vary, making them useful for general medical research rather than breed-specific conditions. While some are rehomed after studies, many spend their entire lives in research facilities. 

Greyhounds

In research, their lean build and strong cardiovascular system make them prime candidates for heart and blood studies. Retired racing greyhounds sometimes end up in labs instead of adoption programs. Their unique physiology helps advance treatments for both human and canine heart diseases, and they are frequently used in studies related to anesthesia and blood clotting disorders. 

Spaniels

Loyal and full of energy, spaniels have been studied in hearing and vision research, with some studies examining their tendency toward ear infections, a common issue in floppy-eared breeds. Their deep bond with humans makes lab environments emotionally challenging for them, raising ethical concerns about using companion animals in scientific studies.

Terriers

Terriers have been used in genetic research due to their predisposition to certain diseases. Some studies focus on their high energy levels and anxiety-related behaviors. Their bold personalities contrast sharply with the sterile environment of a laboratory, making their inclusion in research a particularly sad reality.

Pointers

Pointers are highly active and intelligent and are sometimes used in neurological and behavioral studies. Their strong prey drive and problem-solving skills make them ideal subjects for cognition research. While they are less common in labs than beagles, their use in studies on anxiety and attention disorders has provided insight into similar human conditions. 

Setters

Setters have been used in studies on hereditary diseases. Some breeds are prone to genetic disorders affecting mobility and digestion. Research on setters has contributed to veterinary advancements, but it raises the question of whether progress should come at the cost of animal suffering.
