I didnt realize they 'mark' i mean i have a full grown male uncut german shepherd and he doesnt mark. ???
Anyway, it sounds like 6-7 months is a good time. Im not the sort to put stuff off like this but it sure is hard thinking about it because i dont like that he has to be put under.

I saved my kiddo's teeth, so I can imagine probably saving furkid teeth too LOL
