I'm so sorry to here about your little one. I have two dogs a yorkie and a great dane and when our great dane was about 6mo. she got a hot spot as they call it on her belly and the vet did a bunch of test(witch I hated putting her thru) but they said it was from the pet dander from a cat that was in the carpet from the people before. So you may have stired up something from the old carpet and she will be find now. we changed the carpet and things are great now |
