I’m a admin on a local yard sale page and every so month I see a women trying to post a dog for sale and then posting looking for another dog I never accepted the post I just don’t know why people keep getting pets then selling them it makes me so furious I mean I know it’s not non of my business and I know things happen but still I feel for the fur baby hell my husband won’t even let me get another cat since our fur baby Steve passed away
