Hi. I have a one-year-old female boxer. My problem is that I cannot seem to leave her alone for more than 3/4 hours during the day without her weeing while I'm out. I thought by this age she should be able to hold it longer. She is fine overnight from 10.30pm to 7.30am, so I'm wondering why she can't hold it longer during the day? She has a urinary infection when she was a little puppy, so has been really difficult to house train generally, but she's now doing fine, except not being able to hold it while I'm out during the day for any length of time. Is this normal? All help and suggestions welcome! Thank you.
