Training just any pet dog in order to evade eviction, to help get certain licensing (though there is no licensing for service dogs, actually) to get into certain housing, etc. is also illegal. You have to have a disability. Not just a diagnosis even. Diagnosis does not = disability. Let alone neither of the two, in the OP's case (although I doubt the OP has any issues today, as this thread is a like a year old or something.)
Not only does it take the absolute "right" candidate as far as health and temperament go, it takes a sound dog, in SO many ways. More ways than anyone considers when thinking of training their dog to be a SD or ESA.
Most people who owner-train end up washing out their dog, if they are responsible enough to know when it is necessary, because of SO many varying reasons.
To take a dog that has been a pet for years (or even less, it doesn't matter), and try to train it to be a SD, or even an ESA, without prior necessity
for one, is just wrong.
The fact that we have the right to owner-train because of the ADA is a privilege IMO, and it's because of people deciding to train their "such a great temperament!" pet dog just to get into housing or bring their beloved dog anywhere they go, that we owner-trainers get a bad reputation.
Again, you have to have a true disability to acquire a SD, and a psychiatric disorder/doctor's prescription for an ESA, describing that you are disabled by a mental illness, and that an ESA is part of your treatment plan.
And owner-training or not, for a SD, the dog has to be taught several different tasks, none of which include just basic love from the dog. Those tasks have to successfully mitigate one's disability, and take months to YEARS to train.
If this person were to try and train their dog to be an ESA, it would certainly be easier, but still a complete fraud if this person has no need for an ESA, and if the dog has had no prior training. ESAs are not just normal well-tempered dogs, they are the absolute right candidates, just like SDs, and they are trained exceptionally well to handle all kinds of situations, just not on the same level as a SD.
It's also because of people barely (or hastily) training their pet dog to become an ESA in times like this, that ESA owners are under scrutiny.
So with all due respect, please don't advise anyone that this is a good idea, in a rushed situation especially.
There is MUCH more work that HAS to go into these dogs than people usually account for.
Here is an example of a person wanting, and actually needing, (from her description) an ESA, and asking how to go about speaking with the landlord to provide accommodations for her, and allow an ESA. The best answer talks a little bit about ESAs and the FHAA (Fair Housing Amendments Act). Emotional Support Animal and Renting? - Yahoo! Answers
