Plain-English summary
A new tool called the Canine Visual Function Instrument (CVFI) has been developed to help assess how well dogs can see. This instrument allows pet owners to report their observations about their dog's vision quality, helping veterinarians determine if a dog has normal vision or if there are moderate to serious visual impairments. The CVFI is reliable and can also track whether treatments for vision problems are effective. This could be especially useful for dog owners who are concerned about their pet's eyesight and want to ensure they receive the right care.

Abstract
OBJECTIVE: In this study, we created the Canine Visual Function Instrument (CVFI) and tested its validity and reliability for assessing the quality of vision of dogs. METHODS: We used Cronbach's alpha to test the strength of the consistency of the questions in the instrument and factor analysis to assess whether the questions achieved unidimensionality in the measurement of dogs' vision quality. RESULTS: Our analysis shows that the CVFI is a valid and reliable tool to seek self-reported observations about dogs' vision quality from owners. Our results also show that the vision quality scale has high empirical validity and therefore can be used to determine whether a dog has normal vision or moderate or serious visual impairments. CONCLUSION: The CVFI might have important practical applications in the field of veterinary ophthalmology in two important ways. First, it can be used to determine whether the treatment of dogs with visual impairment improves vision quality. Second, it can be used as a warning system to alert owners about their dogs' quality of vision.
