How soon

[Judith22]

My dog Wolf has been diagnosed with bladder cancer and the tumor can't be removed. This is breaking my heart he is 91/2 years old and one of the smartest most lovable dogs. He is a Blue Heeler/Shep cross.
He is under palliative care with us and so far seems to be gaining weight, but we know that could change quickly and we have to accept that and know we are lucky to have the extra time with him.
My question is I will defiantly get another puppy but how soon is my question. My husband works shift and I am alone a lot, I have tons of time to spend with a new puppy, but I just do not know when to do this. I even thought about now to give Wolf some fun in his latter days, but I really don't think that is a good idea.
I know I could not stand not having a dog, they make your life so much fuller and the love they show makes your days to matter how bad seems so much lighter. I will add I am having health problems of my own and Wolf has been with me through it all.
So if you can make out this mess I just typed thanks, I look forward to your help.
