We all have things we hate people doing around us and our pets. Here's a chance to get em off your chest amongst understanding people;
I have two:
1. When people approach my dogs and I with their dog to "just come on up and sai "hi"" without asking, and then getting offended when I back away
2. When I used to walk my Irish Wolfhound and people said "That's not a dog, it's a horse!". (Funny the first time, after the 5,000th not so funny)...
