I'm not really sure when we would add another dog. Being in the army, it's hard to tell when/where we will be at any given time, and also finding a place to rent. We had a difficult time trying to find a place to accept large dogs (well, at least somewhere that wasn't under 10lbs or 5lbs). Not to mention, hubby & I both love pit bulls, but Army housing has pit bull bans. That was one of the reasons we opted to live off-post because even though his paper work would be labeled boxer mix, I don't want someone accusing me of him being a pit bull, and then be forced to get rid of him or move. I'm not even 100% certain he has pitty in him, but a lot of people think he is just because his ears are cropped.
We would probably get a GSD & actually just talked about that the other night. We both agreed we would want to add a shepherd as our next dog. The exciting part for me though, is hubby has never had a puppy. He's had 2 other dogs in his life which were both adults. But he's never experienced raising a pup... I LOVE puppies which is one reason why I liked fostering for the rescue that I did (they were primarily puppy & kitten but took in older dogs) cause I was able to get my fill puppy breath while helping them find a forever home.
I think when the time is right we will know. Lugar's only 5 1/2 so he's still (I hope) got a lot of years left in him and he is still very much a puppy. It will be exciting when that time comes though. There was one dog at the animal control in my home town that we would have gotten in a heart beat. His face and build looked EXACTLY like Lugar except he was white with brindle patches on his face (cropped ears that looked just like him too), but they do home inspections for all pit bull adoptions so adopting out of state would not be an option. He was so pretty
Hubby even said he wanted him.
