Well starting yesterday, my min pin just all of a sudden started urinating in places he has never urinating in before. It all happened when I was watching a movie in bed last night eating some chicken and he was waiting on me to give him some, but I didn't and when he realized I wasn't going to give him some, he just urinated in the bed right in front of me. then that same night, he went in the living room area where my husband and his brother was watching a football game and he just urinated on his brother. Then this morning, he urinated on the corner of the sofa and the last time, he was asleep on the sofa with my husband and urinated on him in his sleep. My question is maybe he has a urinary tract infection or something and needs to see the vet or is he just being a minpin? And he has no symptoms that maybe he is ill. What should I do.
