So because you failed at raising a well mannered dog, you are going to banish her to sleep outdoors?
Suggestions I have:
Train her. Find what makes her click and work with her. Wear her out before she gets inside for the night. Leaving a dog outside all day will not wear them out. They need one on one interaction. Take her swimming, fetch, training, running...Make her mind work.
When you bring her in, give her something to do. Stuff a kong with peanut butter, or give her a toy to chew on. She is a young dog and needs that type of stimulation. NOTHING she is doing is her fault AT ALL.
Just because YOU failed does not mean she needs to suffer. If you can't full fill her needs as a dog, then you need to rehome her. She does not deserve to be unhappy. That type of dog is a family dog. They LOVE being with people and pleasing them. Why would you want to break her heart?
Sorry if that is mean but I see this all the time and it gets really old. People need to step it up at an early age before the dog becomes a mess and gets forgotten about in the back yard.
