We have a nearly 12 year old Newfoundland dog that was recently found to have cancer that is quite advanced. He really doesn’t have long. We haven’t told our 3 and 6 year olds yet. We are telling them about the cancer tonight and if it naturally leads to the topic of euthanasia we will discuss that with them as well. I know there are a handful of books out there that address pet loss but I am wondering if anyone has one that they recommend in particular.
