One of the things you can try is 'ground tying' him. Always have him on the leash when in the house. Loop the leash through the handle and place it around your waist. That way he doesn't have the opportunity to get too far or out of your control.

When he jumps up, correct him and put him into a down/stay. While you're doing this, stand on the leash (you might want to be wearing solid soled slippers, especially if it's a thin leash). Give him enough slack so that he's comfortable when he's in the down/stay but will be restricted from being able to get up.

The advantage to this is two fold:

1) Your entire weight is on the leash, so it will be difficult for him to budge you.
2) When he pulls, he won't see a reaction from you (keep your hands crossed, don't react).

Only when he settles does he get the "Good Down/Stay!" in a happy voice and a treat. As long as he's struggling, no reaction. He'll learn that the only 'good' thing is the down/stay. This technique uses very little 'negative' training and only reacts to positive acts.

I would recommend calling your trainer. The vast majority will be only too happy to help you. Many will even come over to your house to take an assessment and to give you some tips of how to deal with his behaviour. They may even have another class that may be earlier / more appropriate.

There are many other techniques that may help.

Good luck!
