sorry to hear that about your doggie ...that is sad ...but never give up hope ...i had a great dane that was diagnosed with bone cancer ...the vet said that he wouldnt live long and it would probably be better off to have him put down ..he thought it wouldnt live over 2 more years ...he was 2 then ...my daughter came back crying ...i told he that doesnt mean a thing to just wait and see because you just never know ..well needless to say our great dane max lived to 8 years old ...thats is what they are expected to live ...but if it was my dog i would make sure on the grains and stuff in the dog food ..it is no way good for them ...not even good for humans (due to the way they store the grains maked the grain sweat which causes mold )..i feed my dog the organix dog food and i am switching them over to the raw diet ...i have had dogs that have had tumers in the breast and back and i believe it is what they put in the dog foods ..so now im fixing so that is why i switched to the organix dog food (for a more nutricious food ) and im going further to the raw ..i have done alot of research on tumors and i dont believe they will grow on and all meat diet ..but that is what i have come up with ....and also if it was my dog on the loose stools i would give her a probiotic ,,,that is the good bacteria in the colon ...it will help to stop the runs ..it also help with digestion and helps to boost the immune system ..the good bacteria in your intestines is what helps to keep you from getting sick ...but whatever you decide i will know that is what you feel is best for her ...i hope she gets better ..sorry your friend is sick
