You know, there's no need to be rude about it everyone. Just something I did for curiosity's sake, and I'm sure others have spent money on things I would consider silly... but I certainly wouldn't tease them for it. Besides, it's not like I went broke over $75, LOL.
Sometimes its fun to just spend money on something silly for entertainment purposes alone or just be frivolous and buy something we really don't need but to me dog DNA tests are right up there with throwing your money in the trash.
I am sorry but to me paying any amount of money to have someone tell me that my dog is a mutt is right up there with me paying someone to tell me I have dark hair.
If you had fun with it, great. Just not something I would bother with.
