So I have a Bichon Frise who is about a year and a half old. Recently she started crying for no reason. She's not in heat and we've made sure that our other dog is constantly by her side (it seems to upset her when he's not). It's gotten to the point where even when we're holding her and petting her she's still crying. She is absolutely relentless! Her constant crying and yelping is driving us insane! What should I do?
