"One thing to be warned when looking into a PSD is that they aren't for everyone. You have to deal with a lot of people staring, asking question, those that are afraid of dogs and people that will try and force you to leave because they don't know the laws. You really have to weigh the pros and cons."

I am glad you pointed this out! I think this is an issue that people don't really consider when they think about getting a service animal. In fact I hear people come up to me in public and talk about getting a service dog for one reason or another like its a new fad. There really aren't for everyone. It is a big responsibility. Not only in cost and having to care for the animal every day as you go through your day but you also have to deal with everyone in the free world who wants to ignore your "do not pet" signs, kids grabbing him, people who are afraid of them freaking out around you, people you are just jerks harassing you, etc, etc. And for those people who just want a service dog because it would be nice to have a dog fetch things for you shouldn't have one in the first place because if they are too lazy to take care of themselves they aren't going to be responsible enough to properly care for an animal.

I also think that therapist/doctors should not suggest to patients that they get a service animal. I have known people that this was the case and these people shouldn't even have children let alone care for an animal. It is very irresponsible.

Having said all of that. I think that service dogs can be very helpful for people with psychological issues. I have a service dog, for my physical disabilities but I get anxiety/panic attacks when I go to the doctor and hospital sometimes and having him with me has helped me to deal with this considerably.
