Hi Marie, what a wonderful chap Alfie is
I don't know what you have tried but tuning into that pic its easy to see that Alfie may be an old dog who is perhaps tired but he is content. Many dogs give the impression they are waiting, just peaceful and happy to do nothing. I have sadly had to cope with losing many animals, that's the only problem when you work with them or have large numbers of pets

so I do understand your problems, fears worries and concerns.
Like Spiritalk suggests why not try an energy treatment? Do you use reiki? If you read the bit in my blog about channelling in energies and then place your hands on Alfie and see how it goes. See if he likes it.
If I was you I would sit down quietly with him, and stroke him gently and close my eyes and concentrate on the moment, try and clear your mind and just be with him, you will be able to sense if he is happy. Don't worry, just be you, nothing spectacular, nothing text book or mindblowing, just be you and him. You will know when. At the moment he is undecided and feeling lost too, he wants to be a puppy again and go for long walks running and playing. Old dogs have to take things slower but still love to be included and not left out, left at home alone, perhaps car journeys for a change of situation to see others, or short walks in new places? He is very glad to have found such a comfortable home and really doesn't want to lose you and leave you behind, perhaps you need to reassure him that it is ok to leave you and that you will be ok?
One thing I will say, and this maybe hard to read now........, but it really has helped me cope, is to make plans whilst he is still healthy and you have a stable mind not clouded with tears and grief. Talk to your vet, decide on all the 'what if's' and 'how to's etc find out what will happen, discuss all aspects for a safe and peaceful passing, decide if you will want Alfie to be buried by you or cremated by the vet, decide if you want a casket or where etc. When his time comes you will find it easier if you have this information and then you can make the right decisions hopefully with no regrets later. I like to keep a lock of hair, their collar and I always bury my dogs in a home made wooden casket with a bone and a blanket, it makes it all much easier for them and me.
I do hope I haven't upset you or anyone else by posting this, I was going to PM it but thought it might help others. I wish you and Alfie lots of happy times together
