We have had our rescue beagle for about a year (she is almost 2). House training has been our biggest challenge. She is an anxious and scared dog with an unknown history. She holds her pee for a long time (24 hours plus). In the mornings I take her out on her leash (we don't have a fence) and she won't go. We go through a pattern of going out and coming in and her whining at the door...only to not go. It's getting very frustrating for me. She also won't pee and poop in the same trip outside. I do give her a small treat after she goes potty. I have thought about getting an invisible fence so I can have more peaceful mornings! Any suggestions are welcome.
