hi we have a 3yr old dog name rocco we bought him on the 29th nov 2019 he was ok well behaved untill 2 days ago he is trying to attack /bite my wife when my wife is trying to be loving towards me , if me and my wife are not trying to get up to anything rocco seems ok.rocco lets my wife feed water , stoke , and wash him with no problem untill my wife wants some fun with me , i am not sure what to do at the moment as rocco seems ok with me , and have all ready spoken to vets who have pasted us on to a behaviouist but this dog is suppose to be trained
