Academics at the University of Lincoln have teamed up with a university in Slovakia to study how dogs behave in the owner's absence.
Dog owners are being asked to complete a detailed survey to help researchers analyse the various clinical signs and situations in which problems can occur.
Destructiveness, vocalisation such as barking and whining, and house soiling are among the most common complaints of dog owners.
It has also been established that dogs showing these problems are at a higher risk of a range of other complications.
The researchers hope to apply the findings from the survey to aid the development of more specific treatments and prevention programmes.
