Adopt a German Shepherd from a shelter animal this week, I harvest it up on Monday due to background checks and reference checks that have to go through. I chose the dog that appeared to be a really calm dog in the shelter, especially compared to other dogs around him. My question is, since this is my first dog that I do not know really what to expect when you bring home. 1 of the biggest things that drew me to this dog was that he was so affectionate, and I was told that it raised their entire lives in animal shelters. The results were rescued by the shelter for another animal shelter animal euthanized because it scheduled. He has spent his entire life in such a cage. I'm curious to what I have when he gets here? ¿Gusto he is going to be wild and wonderful I can not leave him alone for even a few minutes without getting in trouble, nor do I keep it around me until you know what's up? The FYI this is my first dog, and although it has done much reading about what to expect and how to take care of a dog, and one that needs to obedience classes and all that. I 'm still not sure how to treat the first week. The lady at the shelter told me to not let me sleep in bed for the first week or as the German shepherds are so think the leader of the "pack" so if I keep the flat in the ground like me. Also some people said not to be sweet and loved the dog as long as this breed of dog needs a firm hand to train. This is not my personality, however, so there is a "nice" way to go about it was that council or false? Anything that you think I should know would be greatly appreciated!
