Thank you for the detailed response , especially the link to the paper . Yeah , I agree that 17 out of 20 dogs having an immune response and an unspecified number of dogs the abstract lists it as several living beyond the expected survival time isn ' t as impressive as they make it seem on the website . Isn ' t survival time just a best estimateaverage sort of thing anyway ? Wouldn ' t it be normal for at least some dogs to live longer than that even with no intervention ? And it seems even less significant given that there doesn ' t appear to be a placebo group . Hmm . And good to know about chemo for dogs being not as intense as it is for humans . I think everyone was assuming it ' s all the same thing and were picturing the dog in pain and vomiting and unable to eat . He does have a pretty sensitive stomach at the best of times , so there ' s probably a good chance he ' d be in that 10 %, but it ' s reassuring to know that he wouldn ' t be in agony for months undergoing a treatment that might not even do anything . I ' ve passed on the suggestion to see an oncologist . My boyfriend is on board with the idea , but his parents are less enthusiastic even though he ' s willing to pay for everything . His mom is worried that the dog is going to suffer and his dad thinks it ' s too much trouble and money to put into such an old dog with other medical problems . I ' m in a bit of a weird situation myself , not being part of the family . I can relay information , but I don ' t really have a say in it at the end of the day . But hopefully if we can convince them to at least set up a consultation that ' ll put their minds at ease . Or at least reassure everyone that they ' ve done the best they can .
