Hi Customer (name blocked for privacy),
Often, this prognosis seems like we are just giving up. Usually not, however. Many times animal problems are compared to similar human ones. This is usually misleading. Animal problems usually move faster, we usually don't diagnose the problem till later in the course of the disease, and because of later diagnosis, treatments are less successful. Economics usually appears somewhere in all this, too.
There will come a time when he is having a great deal of difficulty breathing. We can do a lot to relieve this sort of distress in people, but there is considerable expense, and I'm not sure it is available to vets. Anemia will aggravate the respiratory problems.
Your question was what can you do for him, and how to take care of him. As with people, nutrition is very important. Whatever he will eat and not upset him, give it to him. Balanced nutrition comes after nutrition. Get some child vitamins and give him one a day.
Dogs seem to know what their limits are, so don't force him with exercise, etc. If he wants to walk, take him, but watch him...he will fade fast on a walk, and you may get to carry him part way, if you go too far.
Owners often wonder 'when will it be time?" After being with him thru his illness, you will get to know him better. You will know. Don't jump the gun, but don't put him thru too much because you don't want to let go.
There is a time too soon, and a time too late, and a time that seems right. You will know.
I hope this helps make things more clear. If you have questions, just ask.
