So my question is, do I have to keep those names? On the one hand, those are the names on their papers and everthing. On the other, how is she going to know I changed them after I take them home?

What do you guys think? Is there a standard procedure for using breeder names

PS
the breeder named them "Hopefully Mine" and "Caplan" and I want to call them "Hazel" and "Heather"
