My dog is only 6 years old but he has turned into a grumpy old man. He is a Pekepoo (poodle/pekingnese) and he?

has developed a really Nasty disposition. I'm on the verge of giving him away! He growls at everyone and even tries to bite us. He's taken to urinating in my kitchen as well. A disgusting habit I simply can't tolerate. My grandson (2 years old) moved in with us three months ago and he chases him and tried to bite him all the time. I'm at my wits end! He's never been fixed and someone suggested that if he has that surgery he will calm down. I would hate spend all that money to have the surgery and nothing changes. Please advise
