I have seen 6 puggles in the last 3 months, as well as a cancer causing labradoodle. Each of them outgrew the darling stage, and off to the pound it went.
I rather like the thought of making up a name for mixes, as long as you don't take it seriously. When Radar was younger we were asked about his breed all the time. We finally settled on a North Carolina Minkling. Of course the thought of anyone breeding them is gross.
