[Help] Dog in heat peeing overnight?

Hi r/dogs! We adopted a labrador retriever a few months ago and she is currently going through her first heat. She normally has no problem with house training, but now seems to have issues holding her bladder until we let her out of the bathroom in the morning (which is where she normally sleeps).I've read that dogs in heat will have to pee more consistently, but is there anything else I can do besides lay down more pee pads to prevent messy accidents? Will this have any impact on her current housebroken status (e.g. will she regress into old behaviors and urinate indoors)?Thanks! via /r/dogs http://ift.tt/2sr2NWz
