My current pup is now ten months and is quite in or out, but my god i had never heard anything like it when she was a pup. I put it down to seperation. She was fine when i allowed her to mingle with my other three dogs, but when i could no longer supervise them i would put her in her cage feet away from the other dogs and this is when the crys and screams started, and by eck could she make noise, this would go on until she fell to sleep. As she got older and i began to trust my other dogs more around her she improved massively. It did at first make me think, what the hell have i bought here,
