I do not have direct experience with service animals but my friend does have one . . . .
The only issue and if it is a certified service animal then the legislation, if it exists where you live, will protect you is the attitude of some people but there are strategies . . .
For example, on public transportation, folks might have an allergy to dogs (well, any animal) so that you do have to manage your reactions / anxiety if someone makes a comment. The strategy around this is that she has a cloth sign in yellow with big letters that states that this dog is a service dog . . . .so people know that it has a right to be with you . . .this may not stop glances or comments so . . .you need to be able to go past that . . . . if you drive, this may not be a problem but sometimes it translates into other venues.
Some people are afraid of animals . . . so, if your dog reacts with barking in unfamiliar situations, this may be problematic . . . . when an animal is certified here, it has to go through performance testing to ensure that it does not growl or bark or snap at other people or other animals . . . .the strategy here is to ensure that the dog is well trained and responds to your commands . . . .if my friend is taking her service dog with her to events where there will be the potential for an unusual situation, she makes sure the dog is always under control . . . in the beginning this was difficult for the dog to ensure that she did not bark (the dog, not my friend) but she did invest in professional training and the dog was fairly young and responded very well . . . . the strategy around this is to take the dog, once it is certified, into new situations a bit at a time . . . my friend actually rewarded the dog with mini treats to re-enforce good behaviour rather than to reprimand it when it was doing bad behaviour . . . she was concerned about the number of treats but at that time the vet suggested some type of treat with extremely low calories . . . .I only wish they made them for me because they did smell fantastic . . .
The other issue is doggie hygiene and ensuring that the dog does not leave calling cards . . . and that, if in a convenience store where there is low hanging temptations that it does not nuzzle or take a bite out of candy bars, etc.
All in all, the experience of my friend is very positive with a few adjustments along the way . . . .I also have a friend who is completely without vision and he has had many service dogs over the years and he would not be without one as much for the guidance the dog provides as for the feeling of safety and security . . .. anxiety is another health condition that would probably respond effectively to a service dog also . . . let us know what you decide and your experience . . .take care, kc
