good info...

The OP on that topic may be on to something with it being dog food related. However, he is misinformed on what propylene glycol is... It is not Antifreeze as he states it is in a later post. I would've tried to clarify that with the op on that board but I am not a member and do not have the time to become a member right now. I have had females that Have normal cycles and females that do not have normal cycles that have the same exact diet and pretty close to the same activity level. I think a lot of those issues are related to genetics. There are alot of folks that just breed the dogs to have a litter of pups and not to better the breed so they don't pay attention to issues like heat cycles and other health issues when they make a breeding. Just my $.02
