I am just finding out that I have emphysema, probably pretty advanced, although I am not on oxygen and generally feel pretty good, only get short of breath walking up hills, so far. But I am thinking of getting a dog and going through a program to train it myself to be a service dog, anticipating that I may need help with mobility and certain tasks if I get weaker/more fatigued than I am now. Has anyone with COPD made successful use of a service dog?
