i love my jack russell george to bits but his barking is a constant nightmare i cant go out or leave him for 5 mins its so bad i am thinking of rehoming him, its not that he is lonely for other dog company as he was the same when i had my other dog rosie who is living with my nan now. i just dont know what else to do!

That's what they do! You can try pretending to leave, stay outside the door and when he barks, rush back in, saying "quiet". You need to be very firm, but not excited, because he'll feed off that and get worse - you want him calm. You'll need to be doing this repeatedly and very consistently, do it 10 times in a row if that's what it takes. If, when you're outside he's quiet for even a minute, you come back in, give him lots of quiet praise, maybe a treat, then leave again. It's going to take a lot of repetition.

Also, if he's got lots of toys and chews scattered around and has been for a long, tiring walk before you leave, that might help. squart water in his face, works like a charm If you really want to keep him, it sounds as if the only solution would be a muzzle. Unfortuanately, in some situations, Jack Russell terriers have an extremely high eneregy level. If you are not meeting that energy level by execrcising him every day vigorously, he will cause trouble when you aren't around.

Its also possible that he's developed an anxiety disorder so that when you leave, he doesn't like to be alone. Any veterinarian will be able to do an examination, and combined with the behaviors of your dog, this exame should tell them what is really wrong. He may perscribe a medicine for your dog toi take.
