Pets may exhibit behaviours that owners find unacceptable or distressing. Therefore, many ways of managing pets and their behaviour have been recommended. From this, many training techniques and devices have been developed, but not all of them are humane. They often promise “quick fix” solutions and thus appear attractive to owners. Unfortunately the “normal” pet may respond differently from the pet with mental health issues. The focus should always be on the effect it has on the pet and its short- and long-term welfare.
