i don't think any humane human

would be bothered by a service dog, or a service dog in training. if the
but there are a growing number of people who bring their dogs where they aren't allowed, despite knowing the rules/law. i'm sure we've all seen many,
many lap dogs in strollers, handbags, running around in malls, etc despite signs saying non-service animals prohibited - not one wearing any indication whatsoever that they are a service animal. just recently, i watched a women take her lap dog out of its stroller, let it run around a clothing store until it peed on the floor, then proceed to try on about 10 kids' tshirts on the animal (the t's were removed and damaged out).
i agree that there are many other things, children, smoking, piggy adults, drunks, that do things to a room that require additional maintainence and/or repairs. none of those are morally right - and there isn't a contest to see which of the wrongs is the least wrong
thank you stitch'sgirl for being a foster family!! if/when we retire, it's something we would love to do (for now, we just try to volunteer at the facility occassionally, and take care of our 1 dog, 3 cats, and the feral cat and her 3 kittens we just found living in our yard

).
it's wonderful work you do, especially being willling to go through that heartbreak each time knowing it is for a greater good
