Hi everyone, just looking for a little advice. I have a German Shepherd puppy who will be 7 months old on 20th August. Up until Monday she has been the best puppy we could have ever hoped for in terms of nature, feeding, sleeping, toilet training etc. On Monday after being left alone for 3 and a half hours maximum (her normal daily routine now), we came home to a half eaten sofa. This is extremely out of character for her as she has never chewed anything before - I am aware she is still young however she has never shown signs of being remotely destructive before. On Tuesday she had a go at the other side of the sofa aswell. I am wondering if she may be coming in to her first season? If anyone has any advice on how we can help train this out of her etc it would be greatly appreciated. Thanks in advance.
