hello, i am new here. i have a doberman, he's 2. he was supposed to be my trail dog, but he has a deformed leg and can't carry a pack. i am looking at getting another dog at some point and have been researching. my doberman we all love, but he is a little high strung/nervous around people. i would like a dog i can take out on the trail, hiking, camping, and be around people without worrying, but at the same time guard me if / when it is needed. i love the doberman breed and would like to look at a few others, before i decide which one i want to settle with. can anyone tell me if they have been around both breeds, compare the likes and differences? thanks in advance.
