As many dogs as I have seen in my family, and it has been plenty as my mother bred pugs for show and is a AKC judge, she always was in the thought that as long as the dog is comfortable and not in pain with a problems such as Niki has, let it be. One pug in particular had a mass growing on her leg and chest area. Could do nothing about it. She let the dog be and we kept her comfortable fat and happy until there was evidence of pain and discomfort. Niki should be handled the same way. If the little guy seems to be ok and making it around without much issue, let him be. Make him comfortable and let him enjoy what he can. When the day comes were he is in pain or life is just miserable with his cancer, then euthanasia is the one best possible thing you can do for Niki. Although the thought of euthanasia sucks, it is a avenue you can take to relieve Niki of any pain that you or the vet can not do anything about. Sorry to hear of his ailment and yes, these little guys get to be your best friend and a family member. They all have a personality of their own for sure.
