Hello everyone. We just picked up our 1st pair of ND doelings this weekend. Thy are wonderful but we have a question regarding tattooing. One of the breeders seemed to imply that tattooing was required for registration (that doeling is tattooed), while the 2ndbreeder made no mention of it at all--but still gave us registration papers. Do we have to tattoo her to register her? What is the deal with tattooing? I can't seem to find the answer online. Thank you so much!!
