Thank you everyone for your tips and advice. We are no closer to resolving the problem. Am trying o work out how to get the money to have mark springer cme out to show us how to train him correctly. But at 345.00 it is beyond our means at the moment. I am in two minds about spending the money anyway . If we keep him of course we want him to be trained and not so rough etc with Oscar, but if we only end up fostering until he gets a new home then that is 345.00 we have spent for someone else to benefit from, but also if we do then we at least have given him a good start and the next forever family will have a well trained dog and he will be a good member of his new family.
We have only had him for a week, he has learnt some things, like sitting in his basket when I am cooking tea, he knows how to sit, beg, and lie down. He doesn't wee inside during the night ( which we were told he was not house trained)
The bad part is his humping and being so exuberant and rough with Oscar. He may be 6 yrs old but he is still a puppy at heart. I don't want to give up on him, but really don't know what to do.
Anyway I will try and post some pictures
Sorry if they are big, I have no idea what I am doing
