When thinking about therapy work what I would look for is a dog who is friendly and loves attention but is calm enough to not jump all over people who may be ill or frail. Truthfully the self control can be taught, thought for some dogs it takes longer than with others. There is a fair amount of training that goes into it (or should) so that you have control over the dog in every situation you can think of and the dog himself is confident enough to handle strange things. Wheelchairs freak some dogs outs, they can be taught that the wheelchair is no big deal though. The idea is to have a calm dog that will basicly just sit there and be petted no matter what and perhaps liven up a bit and perform tricks on request. Usually age plays a role, young puppies don't make good working dogs for obvious reasons, they are too puppy-ish Although we have taken puppies into places along with working therapy dogs for people to play with, there is nothing cuter than a puppy right, I've never taken a larger breed pup into a facility though.How do you know if your dog is "right" for service/therapy?? I know it takes a certain personality, but how do you know? Or do you just enroll in a class and you either pass or fail? I would love to do something like this with Dutch. My DH suffers from severe PTSD due to his tour on Iraq and I think just Dutch's presence has helped him tremendously.
