We just went through this with our Aussie. She was draining the toliets and then she would just be laying there and peeing when she was asleep! Now, our Aussie's pee has alot more volume then our Yorkies pee so this was not good.
We brought her to the vet, she did have a bladder infection but they also found a VERY high sugar content. She has diabetes and gets insulin 2X day and she seems to be doing better. She is still drinking to much water and "leaking" even when awake (she's only 8 so to early) so they gave her estrogen pills and will take them 2X week. I guess it's not uncomman for spayed female dogs to have this issue, especially when their bladders are so full.
Our girl is feeling much better now after being on the treatments for 3 weeks, I hope your vet finds nothing wrong with your baby other than the weather. Once we get into the routine with the diabetes, this won't be the worst thing in the world either even though I was very nervous at first. I'm just glad our girl is getting back to her normal self and feels better...you can even see her eyes are back to sparkling!
