Dogs that are aggressive or intolerant of other dogs represent over 50% of aggression cases referred to the Dog Behaviour Clinic.
To own a dog which is aggressive towards other dogs can produce a dramatic decline in quality of life or enjoyment of the human–dog relationship. Owners become social outcasts whilst walking their dog, often going to deserted spots early in the morning or late at night. The pleasures of meeting and being amongst other dogs and their owners are taken away by having a dog liable to fight.
Helping dogs to recover their normal social skills is a relatively straightforward matter.
