| Use a pair of women's underwear and attach a maxi pad inside

By KathyI have a tiny Pomeranian mix that just got done with her first heat. What I did was take some old sweat pants (or just some breathable material) and got a needle and thread and made them fit her. Another thing you could do if you aren't that crafty is, get small little kid underwear and cut a hole for your dogs tail. As for the blood I just put a lightdays pad in there and changed the pad for her every little while. (05/20/2007)
