Dilema.

Oh dear, I am not coping with my new dog at all. George is a sweet heart. A small Maltese, 2@1/2 years old whom I have had for 2 weeks. He was a stud and a show dog. He cost £400 but the breeder said I would get the money back if I returned him with in a week. Actually I don't care about the money.
He walks on the lead well, loves other dogs of any size and sits calmly in the car or in a restaurant.

Problem is that he screams non-stop if I am out of his sight. Even if I go to the toilet or shower and he is on the other side of the door. When I put the TV on he is now barking like mad at it if a sound is made that he dislikes or he takes a dislike to a character.
He has never been toilet trained so soils every where.
I have read two books on dog behaviour and training and followed it to a T, but it makes no difference.
I spoke to a dog behaviourist yesterday and discussed it all. She said she charges £250 but could not guarantee that she would succeed. She said it was severe separation anxiety which is very difficult to cure.

I am really exhausted. I love our walks and he is so sweet, but have to admit I am feeling very depressed about it.
The breeder is happy to have him back. I am so tired and down that I cannot think clearly.
Any advise or views ? Thanks.
