However, some common breeds and mixes used in laboratory research include:
* Beagles: Known for their gentle temperament, small size, and ease of handling.
* Retrievers (Labrador and Golden): Large breeds with a friendly disposition and trainability.
* Terriers: Known for their intelligence and resilience.
* Spitz Breeds (e.g., Siberian Husky): Often used for studies involving sledding or endurance.
* Mixed Breeds: A significant proportion of laboratory dogs are mixed breed, offering genetic diversity and potentially a wider range of traits for specific research needs.
Factors Influencing Breed Selection:
* Research Purpose: The type of research dictates the breed's suitability. For example, a study on heart disease might favor breeds prone to cardiovascular issues.
* Size and Temperament: Researchers choose breeds that are manageable for their research protocols.
* Availability: The availability of specific breeds can influence the choice.
Important Considerations:
* Ethics: The use of animals in research is a sensitive topic. Research institutions are ethically bound to use humane practices and minimize any harm to the animals.
* Alternative Methods: Researchers are constantly seeking alternatives to animal testing, including computer simulations and human cell cultures.
Note: It's crucial to understand that the term "laboratory dog" does not necessarily imply ill-treatment. Research institutions strive to provide humane care for the animals used in their studies.
