No. There are no animals that stay young. Everything ages.
Almost every German Shepherd puppy is completely black when they are born. The exception to this is pure white Shepherds.
You don't, they do it on their own if they hear something.
If a puppy 3 to 4 times a day if a grown dog twice a day
They should do so by their own, if not don't worry. Its fine.
It depends on the individual puppy. Rottweilers and German Shepherds have some similar temperament characteristics, but also some strong differences. If you're thinking of getting one of the two, the German Shepherd will probably need more stimulation, while the Rottie will be calmer and more level.
Purebred German Shepherds will have pedigree papers that prove registration to the Kennel Club and means that they have atleast 3 generations of pure recorded family history. If a German Shepherd does not have pedigree papers then it is either crossbred or wasn't legible for registration as a puppy. Currently, only shorthaired German Shepherds are shown seriously, so Longhaired German Shepherds may not be Kennel Club registered but still be purebred.
In my experience, German shepherds have varying degrees of being affectionate. To their owners/family they can be very affectionate, caring, and gentle. To strangers or not close acquaintances, they can be standoffish and aloof. It depends greatly on that particular shepherds personality and the socialization they receive as they grow up.
depends on the age puppy 1-16lbs 6mos. old 45-65 full grown 110-135lbs all of my shepherds wieghs around the 110-150lbs range with big bones and all muscle they are all working shepherds.
German shepherds are also called Alsatians.
There is no information on the actual cost of the Gosselin's German Shepherds. Those dogs were not German Shepherds but a mix so not much.
German shepherds come mostly in brown and tan colors
no. White German shepherds are not recognized by the K.C
