What a great idea... to have a dog playgroup! How do you tell all your Schnauzers apart?
I love my dog park. I live in Michigan. I have an Akita. They are usually dog-aggressive, so in order to socialize her, we started taking her to a dog park at 3 months old. We have an annual membership and drive an hour to get there. It has been well worth it, though! We now have a very dog-friendly pup!
