I have recently read about dogs going through a fear stage. What is this exactly? What type of things do they get scared of? At what age? He's 5 months old. My Dal is scared of going out to the toilet by himself at night time (we are still waiting for our landlord to fix the outside light so it is quite dark). If he is going to have an accident inside the house, guaranteed it will be a night time! During the day he's toilet trained but only semi-trained at night times!

I have problems with my Dal wanting to go outside by herself. She never will stay out there with out our other dog. I think it is because of being in the pound. I would love for her to feel more comfortable being alone. She is like a little shadow, constantly following me every where. If she accidentally get closed in another room she freaks out (barking, scratching, etc). I have been really patient hoping a little time will help her over come being alone. I am only away from the house 2 hrs a day. She nearly chewed through the bathroom door. Now, I keep her with the other dog, and she does fine.
