My little yorkie piper has been acting funny these past two days. She is a year and 4 months and 4 lbs. She is not spayed. Yesterday she was acting really lazy. Was not playing just laying around the house. I just thought it was because I was off so I was just sitting around the house and she's very attached to me. Today she is having muscle tremors is her back legs. She is urinating but I have not seen her poop today. Mind you she still has accidents in the house but I haven't noticed any poop. Due to the fact that I free feed them I am not sure if she has eaten. When I take her outside she isn't her normal hyper self. Does anyone know what this could be?
