Is this unusual behaviour for her?
My 2 older dogs have "bladders of steel"! My old female has held it as long as 14 hours. She holds it close to 12 hours on an almost daily basis. I let her out in the morning when I get up and she usually just lays on the porch. She doesn't "go" until several hours later when I go out to feed the horses. My male heeler is the same way. Neither have ever had ANY Urinary tract issues. And with them being 10yo and almost 9yo, you would think if it was THAT bad for them to hold it that long, they would have had some sort of issue or infection by now.
