Ok... My chi, Jadie, is in heat. She's had some spotting and stuff like that, and i was wondering how long the cycle lasts. My mom went out to Petco and bought a pair of "Puppy Panities and a Pad" (that's exactly what it says on the pacakge). Jadie doesn't like it, but she has to wear it. If anyone could help, that'd so awesome. Thanks so much! <3 <3 <3!
