We recently got a GSD (2 months ago). My parents have had GSDs my whole life but this is the first time I have had one of my own. Anyway, he is beautiful and well behaved, very intelligent and in fact I can't complain at all except for the fact that toys last about five minutes until he chews them to pieces .
He is at home alone (in the garden with a kennel) during the day. We have a dog walker that walks him for an hour at lunchtime. He seems fine, but I wonder if a second dog would be a bit of company. However, I have also seen many an example of owners thinking that they are doing their dog a favour getting a 'friend' and they end up with a nightmare when the dogs don't get on, or the original dog is victimised. I am also not sure that the 'new' dog might not lead our perfect boy astray or that the two of them might get a bit too mad if they do get on.
'Why are you bothering if you are so worried' you might say? Because I think if they get on it could be great for him, he is a lovely dog and he needs somebody to play with. A girl can only tug a rope for so many minutes a day and if the second is as lovely as he is it would only be a good thing! What do you think?
