I think the problem with the economy is that there are too many dogs flooding the market. It would probably be better to slow down how fast dogs age, rather than implement an artificial process of puppy limiting. If dogs aged 2 or 3 times slower, they would reach breeding age slower, and go into heat once every 2-3 weeks, rather than once a week. this would reduce the number of pups on the market a significant amount. Are you for or against this? And why? Can you think of something to add to improve this idea? Edit: If your not for slower aging, then how about just spreading out the heat cycles further?
