Are there any successful dating sites that have millions of members geared only towards people who own pets? Where people post themeslves w/their animals. Have many sites tried this gimmick and failed? Have they ever been able to compete with match.com or eharmony, pof, etc. Thanks for any info.

While you're on the dating site, there's usually a feature where you can send private messages to each other. When you're messaging each other to get to know each other better, one of the first questions you can ask is whether they are into pets. I doubt there would be any dating sites geared towards people with pets as a major theme.

What's the problem that you're having now with the dating sites?
