Dog was castrated on Thursday and has now started weeing, he has one it twice on the spare bed. I only got everything washed and dried yesterday and again he has done it this morning at seven am. He didnt bark to go out. He also did it on the kitchen floor when my DD was getting ready to take him out yesterday first thing. Is this normal after castration and will it stop. How can I stop him doing it on the bed again. He has been good up to now and always waited to wee outside.
