Im thinking of buying a german shepard and have a few questions i would like to ask about them?

males like men more,ours loves men and hes a gruad dog big bark and big bite lol,his dad weighs 130 pounds!!!our male stays with little kids and follows them around and greets them whenever they are outside,females are more calm I think,they cost betweeen 400$:/we spent 160$ on ours hes a big puppy and btw way if your getting a pupy..dont they take forever to grow up,I'm kidding ours is 6 months old and he chews everything and anything,he chewed up his bed,he wont chew bones or toys and my border collie is more mature than him!hes 10 months and he acts like hes a 3 yr old differnet breed but theyre both dogs right?.by the time they're 3 they finally are done with the puppy stage.good luck go to your shelter and get one thats a year old:}
