Dear Johan,
You have come to the right place for support and information. I am so sorry to hear about your 6 year old puppy. The diagnosis of cancer in our best friends is just heart-wrenching. Our 6 year old schnauzer Benny lost his battle last Thursday to Mast Cell Tumour cancer. He had one surgery and then after months the tumour reappeared and no surgery or chemo or radiation but we did everything to boost his immune system which gave us nine more months.
You might want to contact Dr. Dressler who has excellent advice for people who have dogs with all kinds of cancer. He lives in Hawaii and has a "blog" where you can put you questions and he answers them for you as best he can. I got lots of help during the months Benny was ill.
Here is the link to his website:
Problem Solving while having a Dog With Cancer Sure hope this helps.
Also Ted's book is filled with valuable information and really worth downloading. Good Luck! BTW, I used
Essiac capsules for Benny and many other supplements as well which definitely boosted his immune system. You could also brew some Essiac tea and put it in the food.
God Bless You.
Joanne
