In a way, I wish there was proof needed although I certainly know how difficult this would be for OTSD's and would perhaps make all of us incur costs we can ill afford. We went to the pin event at Epcot this year and saw several service dogs. One was accompanying a guest with an invisible disability but was very well behaved, obviously trained, and was a chihuahua. On the other hand, there was a woman with TWO small dogs, each with a different color vest, both with a "hearing dog" patch, not "dog in training". The dogs were totally misbehaved, pulling the woman all over and running amok even though they were on leashes. There is no reason someone needs two hearing dogs and I really doubted they were SD's. Because of their poor behavior, because someone was in a public place where pets are not allowed with two dogs (which is very questionable as one was not in training with the other working which would be the only reason for two dogs) those things affect public perception and strain the places of business who need to accommodate the disabled with SD's. Disney bends over backwards to accommodate us but how long will they tolerate people claiming pets or emotional support dogs as SD's and allow them in the park, esp. when they are seen to have poor behavior. I have to wonder what liability they would have if one of these pets bites a guest.---Kathy
