deteriorating shoulders and need to transfer a little less due to bad skin integrity
ummm...this is the reason a lot of people in wheelchairs get a SD. In fact, I think that maintaining your physical integrity is THE reason people in wheelchairs get a SD (besides retrieving).
Honestly, only you and your treatment team know what's going on with you. This nurse online has never met you and never spoken to your doctors. Just ignore her and do what you and your doctor think is right for you.
Do you think that every person (or even every medical professional) is going to think that a dog is right for me? I can hike and jump and climb and swim (most of the time). I see (with correction) and hear perfectly. I don't have seizures, fainting spells, or moments of complete disorientation. What do I need a dog for?!
I'm getting a dog because: 1) my doctors have stated that I am indeed disabled after I carefully showed them the ADA and supplemental materials about the standard for disability under the ADA. 2) I carefully drew up a task list and went over it with each of my doctors. Each has stated that they think that the tasks my dog is going to perform will significantly increase my independence and functioning. 3) I personally know myself and my illness better than anyone else out there and I think that a dog will increase my independence and functioning.
Don't let one person who doesn't know what she's talking about rain on your parade. If you (and your medical professionals) think this is right for you, charge ahead.
