yeah my boys are full grown now and I am hoping that when I take them in for their health check that the vets scale will give a more accurate (and lower) weight! haha Now I just need to find a carrier big enough for them both, but small enough for carry on. UGH... this is not easy! Northwest allows 2 dogs if they are siblings under 6 months also. My boys are siblings (litermates) and never have been seperated since birth.... but they are over 6 months! I have NO idea why age factors into this!
