Scientists have found out under what conditions dogs live longer.

To do this, they analyzed data from 21,410 animals. It turned out that dogs were less healthy and mobile in families experiencing financial or domestic difficulties. However, cheap food and lack of toys had five times less effect than the lack of communication with relatives. Best of all, regular games with other pets affected the condition of the dog. But a large number of children adversely affected the health of animals. The researchers also found a positive relationship between family income and the incidence of disease in dogs. This is probably due to the ability of owners to take the pet to the vet.
