Help! Our 9 month old Lab got neutered 10 days ago. This past weekend, he has peed in the house twice, chewed up his entire bed, jumped on our dining room table, and just peed on ME while laying with me on the couch. NONE of these things have ever occurred. He has been an excellent and well-behaved dog since day one. He was fully potty trained at 10 weeks. He has never exhibited such negative behavior. All the research shows that this is not common after a neuter. Any idea what's going on?????
