My ESA doctor provides a letter not a license/certification.
To add to Madra's post:
...and a letter will not allow the dog to have all the permissions of an ESA animal, like being exempt from breed-specific legislation, going places with their owner, and being safe from being evicted by a landlord. But anyway- the info there was good, the whole "give us money, we'll send you a letter" thing is off, though, since the medical professional has to actually meet with the person and prescribe the pet for the exemptions given to an ESA to apply- these exemptions only apply to
certified dogs.
But,
@Impetuous me , your ESA dog seems to be actually certified. So unless your landlord decides to find a loophole by finding a new reason to evict you, you should be safe. In most cases, a simple discussion will solve the issue, but if that doesn't work, you are the one in the right should this be brought to court. Even if the landlord tries to evict you for another reason, you could probably sue him and get a settlement of some kind, if that's your thing. I'm not real big on taking people to court, but I get that it's necessary sometimes.
