I know we learn things as we go along in life, but I am curious why the standard was always 6- 8 wks in the past. One of the best dogs I ever had was a chow-cocker mix that I took home at 4 wks. I did this cause the situation the pup was in was terrible. She is the only one that made it out of the litter and they died after we got Maggie. Is it only the toy breeds that say 12 wks. I have usually gotten at 8 wks. I am doing research on poms and wonder if 12 wks is best there too. Just wondering, not trying to debate the issue.
