As others have said, visit several clubs at least a couple of times and be aware that the club you start with may not be the one you eventually end up with.
When I first looked into clubs I visited two. One was smaller, very welcoming, not as many titles each year and only one trial. The other was huge, lots of trials a year, many members titling, not as welcoming, though friendly, and the whole atmosphere was a bit much for me. I was not a novice in dogs, but I was just not comfortable with the latter club. I joined the former. This is the club where I got my tracking foundation and got a good introduction to SchH. We had a picnic every year, people had fun together, we trained dogs.
When I got Treue I knew I needed something different, some stuff happened in my current club with new members that I didn't agree with so I moved on. I trained on my own for almost 2 years and then I did the pay to play route for 6 years. I learned a lot about protection (some very good, some not so good), learned how to appreciate extremely strong dogs and titled two dogs. This group titled many dogs, had one or two trials a year, but was very much "my way or the highway" type of group. The atmosphere was also toxic at times. Eventually this group no longer served my purpose so I again moved on.
In 2003 I actually joined the second of the two original clubs I looked at in '92. I wanted a mixture of a serious club with the social atmosphere. I also wanted more control over my own training and the options to learn more. The club's dynamics had also changed and the people I didn't care for 11 years before were no longer there. I am still a member of this club (well, I am president and TD of the club
) and also train with a second club when I need people that can bring me their EXTREMELY experienced eyes. This works very well for me.
Be prepared to do some driving like Lies mentions.
