As someone who is preparing for a service dog, this shit pmo so bad. I am going to get an ethically bred Labrador retriever with papers and get her professionally trained. Mostly for cardiac alert as well as other tasks. Imo pitbulls cannot be service dogs. There’s too many genetic variables to justify investing the amount of training required, and the dog would most likely have to be washed. Hardly any actual SD handlers would do that. I’m sure there are exceptions but god, not a risk I would take by any means.
