Aaron so sorry to hear this. I'm glad you guys are ok. Me, I'm a gun guy but if you're not comfortable around guns and unless you know for a fact that you could pull the trigger on someone don't get one. If you know the work and care involved with a dog and are good with what it initials then I say go for it. My vote is for a Doberman. My family has had several and they are awesome dogs. My sister had one that was professionally trained for guard duties but was the sweetest dog. My niece was little and would crawl all over her. I also had a Dobbie and she was a great dog. If someone came over that she didn't know, she put always herself between them and me until she trusted them but would not be aggressive toward them. Every time I let her outside in the backyard she would make one lap around fence to check everything out. I always said she was on patrol, lol. Dobermans are very protective of their families, the females even more so. I am a big fan of rescue dogs, I have one now but in this case you may want to look at buying one. Go to a legit breeder and spend some time with some dobermans I think it will be just what you're looking for. Stay safe my friend!
