heres my staff with cut ears, my vet told me they do crops up to 5 months old.
this is a show crop
reason i had them cropped was that when she runs it would flop over and bother her she would actually stop running and shake her head to unflop them. now she runs like a bullet
they dont crop ears in MA either i had to drive to the next state to a well known vet that does most of the show dogs around here... if you plan to get them cropped make sure to see the vets work before hand and bring pic with you to show them how u want them cropped.
crop dem ears, your dog will love u for it
