At what age are GSD's considered adults? My vet said at a year old and I've read online that it's when they are 2+ years because they are still developing until then.
I think they do. Physically they mature quicker but human females do as well. Mentally, it's hard for me to say. Faren is serious about everything except getting off the bed when I tell her to. Then she thinks she's funny. Seger is just a fun loving soul.To further confuse the issue, many believe that females mature earlier than males.
