Write as many details as you can. It’s important for our first one on one appointment.
Regarding the questions about behaviour try to describe as much as you can.
Statements such as « my dog is attacking other dogs » do not give enough details to understand the situation. I need descriptive facts such as « my dog growls as soon as he sees another dog (even if he is 200meters away) and if he gets closer, he tries to bite him ».
