Cindy's Answer

The first thing I would suggest is to have the vet check a urine sample to rule out a bladder infection or some sort of UTI. It's not that uncommon for puppies to have a UTI and that may be the issue.

If she is having accidents in the kitchen when she's gated off, I might take away that option for now while you sort this out. Keep her with you or in the crate. If she doesn't have a UTI, then it may be that she's drinking more and with the larger area of the kitchen just goes when she feels like it.

But, the first thing to do is rule out a medical problem. I hope this helps.
