I have had a German Shepherd in my life since I was 1 year old. Presently, I have 2, an 8 year old plush-coated female and a 5 year old plush-coated male. They are as different as night and day.
Female -
Good - the most devoted and affectionate dog I have ever been blessed to know (ok, GSDs are loyal and affectionate, but she had a bad start and is bonded to me as no other dog has bonded before). She will give her life in an instant to save her pack, and that includes her cats. She is also a great judge of character, and if she does not want you near her pack, there is a reason for that. Smart as can be, which in her youth meant that we were always aware of needing to remain Alpha. I happen to like a dog that does not let me get complacent with obedience, so she is perfect for me.
Bad - Her fears! she was malnourished and frightened of everything when she came to us at 14 weeks old. A pillow fell of the sofa, she would jump out of her skin, soil herself, and try to run away. Years of patience and she is better, but she will never be the typical confident GSD. Her need as a puppy to always lay against me, with her head near my heart, became a nuisance, but I miss that as she started to feel more secure. Also, her prey drive is beyond anything I have ever experienced! In her prime no squirrel stood a chance! She has even caught crows as they flew out of my garden! This also meant that she chased down visiting children (not to hurt them, she just wanted to have playmates, but if you didn't know her, that could be frightening!). That we were never able to train out of her, so she had to be on a leash until she calmed down. Also, the shedding! Plush coated, wavy haired German Shepherd fur is always present, everywhere.
Ugly - The ugliest is the hereditary diseases of GSDs. She is dying, and though she has not given up yet, we know the end is very near. I hate that.
Male -
Good - typical confident, goofy, adorable, protective German Shepherd. He is huge, all of 114 pounds, and plush-coated so he looks even larger. He loves being with his sister dog, but his humans are always in sight. He wants always to please, and when I call him to me for training, he starts to go through all the commands on his own just to get his treats (I have to mix up the commands on him!). My boy does not have a bad-natured bone in his body. If I could have 10 of him, I would be thrilled. Those that don't know him, fear him and his deep bark (great protection), but the second I accept you, he is a big cuddly hunk of fur that just wants a nice rub behind the ears.
Bad - Teeny tiny bladder. How does such a huge dog have such a small bladder? My female could probably hold it all day, but my boy, he could pee every hour given the chance. Then there is the shedding! Sure, the plush, wavy hair is everywhere, but now add it to the body of a 114 pound dog, and there is even more of it! Also, his need to save us from the evil pool. He will dive under the water to try to pull us up when we dive down. Claw marks from a frantic dog under the water when you are trying to grab more rings than your husband in a pool game is no fun! His sister will just watch from the stairs because she is smarter than him and knows we are fine!
Ugly - as long as he stays healthy, there is no ugly with him. Ok, his gas is awful, but if he lives a healthy 15 years, then no ugly here.
