I'm bored so I'll say some more lol.

German shepherds are, as said, very good guard dogs. So you should always have signs that says "beware of dog" AND "Do not trespass" because if a GSD feels the need to protect it's yard or home (which one almost always will) it may bite, and the injured person could sue. One of the reasons I live GSDs so much is the fact that one is willing to protect so much, and will fend for it's family until the end. Such a dependable breed.

GSDs shouldn't be kept on puppy food for very long, because the extra vitamins might make it grow too fast. A GSD that grows quickly is a very bad sign. Considering the vulnerability they have to bone diseases (my own RB shepherd Polar died from a bone disease. He was over 100 pounds and still just a pup), they should be put on a food that will let them grow slowly. A shepherd should be able to grow until about 18 months to two years.

Although it isn't very true that shepherds are more closely related to wolves than any other dog, they are supposed to have the most wolf lineage in their heritage. Either way, they do resemble wolves quite a bit. There was a big research project where they took GSD pups, husky pups, malamute pups, and samoyed pups, and they gave them to a wolf pack. The wolves took care of the shepherds and abandoned the rest. No one is quite sure why, but it does bring up alot of question as to why they would choose pups of one breed and not pups of the other.

In North America, the colours that would be excluded from conformation are white (unless they are doing a "american white shepherd" show), blue, and liver. Blue and liver because the pigment of the nose isn't black. The nose colour has to be black.

German shepherds are sooo smart. I've never met a dog as smart as my Leather.

I find that shepherds aren't as inclined to be crazy about balls or sticks like a border collie or springer spaniel might be. They love to play, but I find they lose interest quickly. I love this, becasue I don't enjoy having a ball placed in my lap every five minutes lol.

You have to teach a shepherd manners. Make sure it knows that you are allowed to touch it's food. They can become very possessive of their belongings, maybe not with the owner, but even other people. That's why Leather doesn't get as many chewy treats as she used to. One time she started growling at any who walked by, so she was scolded and had her chew taken away.

I'll come up with more later lol.
