Wells....I think that the composition of couples/singles depends very heavily on the demographics of the geographic region that you live in.....
Yeah, I agree with the idea of holding off on a dog if you want to expand your social life, more. The logistics can be hard. One thing that I found out that can help...if one has the ability to do so...is to have a dog door and a securely fenced yard...(we had an electronic fence, at one time, that worked like a charm). We lived on a very large corner lot with a lot of pedestrian and auto traffic, which supplied a lot of excitement for the dogs. Of course, our dogs were ones that we "saved" from being taken to a shelter--we never did go searching for a dog or cat!
Yikes...it seems that with dating as pet ownership, a lot depends on location, location, location...just like the old real estate saying.....lol.....
