My wife and I traveled quite often and our Doberman stayed with different people in the family from time to time. He did great and was super adaptable to any situation. He has stayed with my parents, my wife’s parents, my brother-in-law and some others. I think the longest trip we had was 3 weeks, which was a bit on the long side… but one-week trips here or there you should be totally fine. So no, they’re definitely not dangerous in someone else’s home. No, at all. Just make sure you socialize your dog a lot when they’re young with different people. Especially with those (like family for example) that they might be staying with in the future. They’re much more likely to not miss a beat and will try and climb in the laps of your family while they’re watching TV to cuddle!
