Shih Tzu Q&A
A GSD's ears will start to grow cartilage anywhere from 4 months to 6 months and they will be solid usually by the time they are 12 to 15 months.
i really dont think theres an age to when their ears start standing up my gsd's ears didnt stand up till he was 2yrs.old and my father gsd's ears didnt stand up til she was 10months old so i dont think theres an age
my puppies ears were standing straight up @11 weeks when i got her
my GSD's ears were sticking up at 2 months so were her brothers but not the rest of the litter. so i think it depends on the dog
it really depends on the dog, some of them will never stand up properly. it is recommended that you don't pet their ears back though until the ears are standing up fully to prevent the soft cartilage from being damaged.
Our black german shepherd's ears stood up tall when he was about two months old. At first it was just one ear for about two weeks then both were standing up tall. But it probably just depends on the dog
