We adopted a Great Pyreness/Yellow lab or Golden Retriever cross from the animal shelter during the summer. She is now about 11-12 months old probably. She's been a sweetheart but still a bit playful so we aren't trusting her with the chickens yet. We turn her out in the yard as soon as the chickens go up for the night...around 4:00 pm right now. In the last couple of weeks she has refused to come into the house when we go to bed. If it's very cold, she will scratch on the door around 4:00 a.m. to come in. We have tried to get her to come in but she refuses. She does apparently walk the perimeter of the yard and all around the coops all night long and will bark occasionally at whatever it is that she sees or hears. The problem is that the last few nights have been in the mid 20's and when we go out during the night to try to get her in, she is laying on the concrete patio and is obviously a bit cold. While I love that she is learning to protect her home and the birds, I hate her to be out in this frigid weather. I bought her a nice bed from Pet's Mart yesterday that is made of ripstop material and filled with a combination of polyfill and cedar. I plopped it down in front of the woodstove and she has been laying on it since. My plan was to keep her in at night until it warms up a bit and then put her bed inside the barn, but leave the door open so she can still roam the property if she wants to. We'll put one of the oil-filled radiant heaters beside her bed in the barn. Any other suggestions?? Also, at what age do you think we might be able to begin to trust her around the LF girls? She would never be with the silkies as they are in large coops with fenced turnout paddocks. Because she is a cross, I try to keep in mind the "other side" of her disposition.
