What is Animal Welfare?

Animal welfare is how an animal is coping with the conditions in which it lives. ​

How do we know how well an animal is doing?
“An animal is in a good state of welfare if (as indicated by scientific evidence) it is healthy, comfortable, well-nourished, safe, able to express innate behavior, and if it is not suffering from unpleasant states such as pain, fear, and distress.” -OIE  This can be assessed through internal and external physiological measures as well as behavioral measures.



“The welfare of an individual is its state as regards to its attempts to cope with its environment.” 
– D. Broom

Evolution of the Dog-Human bond

Knowledge about how dogs evolved and who they are today provides the justification for the protection of their welfare, illuminates specific areas of risk, and informs the interventions required to ensure their welfare is good.  

Canine Welfare Science Curriculum

Comprehensive dog welfare requires attention to all areas that impact welfare status. Convenient and easy to use, the curriculum makes evidence-based information readily available.   Together, with knowledge and effort, we can improve the welfare of dogs.
