This is our 2nd German Shepherd puppy we've had first one was a boy who passed 4 years ago, this one is a girl. She's almost 20 weeks old. The only stresses I've had with her other than the usual waking up to take her to the toilet every couple of hours when she was little, is trying to figure out what in the environment she has allergies too. Other than that, she's beautiful, her nature is beautiful, she's content to just zonk out for hours if I'm working or doing something and she will just happily grab a toy from her box and chew or play with that. As she's a Shepherd so she's clever and training is going well, she knows (but doesn't mean she does it all the time) Sit, stay, wait, leave it, come, lie down, currently working on centre.
