Undesirable behaviors exhibited by dogs are called canine behavioral problems. Behavioral
problems are common among dogs kept in ordinary homes; hence, veterinarians need to have
sufficient knowledge of these problems, so as to advise owners. Among dogs kept in
ordinary Japanese homes, only a few behaviors have been investigated regarding prevalence
and relevant factors. To improve understanding of behavioral problems, a comprehensive
survey is crucial. In this study, we distributed an online survey including general
information and questions about 25 canine behaviors that can become problematic to owners,
to investigate (1) the prevalence of behavioral problem, (2) the most common behavioral
problems, and (3) the relevant factors of each behavior. We collected 2,050 valid
responses. Among all dogs, 86.0% exhibited at least one behavioral problem. “Barking at
noises inside the house”, “Barking at unfamiliar visitors”, and “Pica” were the most
frequent behavioral problems. To reveal those factors related to the expression of each
behavior, we performed multiple logistic regression analyses, with the presence of
behaviors as objective variables and dogs’ general information as explanatory variables.
Breed, age, the presence of other dogs in the household, sex, neutering status, source of
acquisition, and type of residence were associated with 19, 16, 5, 4, 4, 4, and 1
behaviors, respectively. This study revealed the prevalence of 25 canine behavioral
problems in Japan and relevant factors of each behavior. Our findings will be useful for
veterinarians in advising owners about preventing behavioral problems.
