First I am a dog lover!....but dogs & "some"people do not mix! I have found that a lot of people are terrified of dogs, and taking a dog where alot of people will be congregating, such as a yard sale for instance is not a very good idea....in fact just today i was in a restaurant and there was a service/medical dog in there,a black lab,and was out fitted with his service/medical signs & gear, he was laying on the floor, not in the way or anything, and a young lady walked by and noticed the dog there and almost had a heart attack! it scared her so bad, it wasn't a pleasant site to see.
