I say that people should take some sort of questionaire before adopting a pet to see if they show any type of?

aggression towards animals. do you think this a good idea and if yes please tell me why?

What is the process for training my dog to become a service dog? What sort of programs are available?

I foster strays and am interested in training them as service dogs. I would be interested in therapy, guide dog training, service dog training, or anything else along those lines. Does anyone know any resources?
