My dog is of the tall, friendly, he wants to meet every human who looks at him variety. This is great if the human likes tall, playful dogs. It's not so great with people who have fear of dogs.
A dog bite is not nice and even a nip that doesn't break the skin can put a person off dogs (and dog owners!) for a long, long time. So, as a dog owner I keep mindful of that fact whether I bring Shadow to Vallarta-Ast DGC ( where dogs are allowed... leashed, under control and permit in hand) or simply walking him in the city. For city walks he has to heel on my off side if we pass people and I make a point of being obvious of directing him to the side away from a human to give the person a chance to notice that I am moving my dog away from them.
At the course he is clipped to my bag at all times. He does slow me down and consequently when I bring him I usually play by myself or with the friends that know him and enjoy his company and don't mind slower play due to his always having to sniff everything. People behind me are allowed to play thru. Bringing him to the DGC messes with my game. He is a distraction, but I knew that when I got him...owning a dog means paying attention when we are out and about-anywhere.
There are 2 courses in Madison (Madison has strict dog laws. NO DOGS in any city park at any time. Stiff fine and the law is enforced), that expressly prohibit dogs. Posted at the first tee. I do not bring Shadow to these courses, but some people do bring dogs. Some of these people allow there dogs to roam and crap and be a distraction to others. This human behavior kinda spoils things for the many responsible dog owners.
Although I wish people wouldn't bring dogs to courses where dogs are not alllowed, I tolerate it cuz I like dogs, but not necessarily the dogs' owner.
Dog behavior is interesting and I suspect that most owners don't have much of clue of what their dog is thinking/feeling when the dog interacts with humans or another dog(s). It's really their loss.
If you really want to learn about what can happen with humans and dogs, go to a dog park about 5:30 in the evening and watch the wackiness. Dog parks are crazy at the after work hour. People are tired and dogs are frisky. Moms bring kids. Guys with pits wear Ipods or cell phones glued to their ears. Young women carry puppies. People bring fast food (MEAT!) into the park. People treat other dogs without permission. People gather and flirt. Who's watching the dogs?
There are even people who are hostile to another dog interacting with their dog. ???
The dogs...on the other hand are kinda like 6 year olds (with very sharp teeth) at the playgound. Dogs have a hiearchy. Dogs have temperments and personalities. There are bullies, gang bangers, studs, whinning babies,teaser/mischief makers and good dogs. Left to themselves, a group of dogs will likely figure things out with a nip, a growl or even a severe take down. This can develop into something like a hockey fight where the guy who threw the last punch gets the penalty.
Love your dog and be responsible.
My observation is that many folks aren't seeing what is going on before a scuffle breaks out.
