I'm just a Lab Retriever that enjoys Freedom. 

Now if I can only figure out where to store that info where I can remember where to retrieve it in 20 years or so...    

However, real service dogs are virtually always highly "trainable" breeds, such as labs, golden retrievers, labradoodles, and herding breeds (border collies, corgis, etc.)

This is located in a city area where you aren't going to see golden retrievers , labs or real dogs.

For receipt / confirmation and more important messages I'll send an email which I then can file in specific folders in my email program (which is just Gmail) for easier retrieval later.

I personally would prefer email so it's easy for them to turn in, easy for you to retrieve, and you have a digital copy for future reference. 

I know some of the private trash services around here will retrieve it from next to the house but it sounds like you have city service. 

They paid the money to get me the screening that I needed but when I went in to retrieve the document's it said that it could not "verify me" even though it recognized my login and password and all security questions.

Most of the time they paid up and retrieved their car before sale.

The family retrieved everything almost immediately, and of course some investigators came and looked over everything, but since there was no real legal issue, we re-listed almost immediately - without telling people the last tenant passed away there and it might be haunted of course...
