The Canine Brief Pain Inventory (Canine BPI) is a psychometric evaluation which allows owners to rate the severity of their dog’s pain and the impact of pain on their daily functions. The evaluation is a validated questionnaire that asks dog owners four questions about the severity of pain evident in a dog (the pain severity score) and six questions about how pain interferes with a dog’s activity level (the pain interference score). The questionnaire also has one overall impression score, and although not used in the final calculation, it is useful along with the calculated score in order to assess whether a form of treatment (e.g. medication, surgery, supplementation) has had a measurable effect.

When first developed, the aim of the program was to develop a scale that:

  • Was owner completed.
  • Would take only a short time to complete.
  • Would be easy for owners to understand.
  • Would capture not only pain severity, but also the perception of how pain interfered with daily life.
  • Would be valid and reliable in a variety of chronic pain conditions.
  • Was analogous to a scale used in human chronic pain studies, which would facilitate capturing the cross species translational potential of canine chronic pain studies.

Further information on the Canine Brief Pain Inventory is avialable from the website for The School of Veterinary Medicine at the University of Pennsylvania.



Canine Brief Pain Inventory Questions

Each response to the questions will be assigned an individual score, which collectively will help to provide an overall assessment rating, which will help to determine the degree of joint pain your dog is experiencing. The higher the final score the greater the degree of pain, whilst lower scores represent less discomfort.
