My 16 year old Magnum was recently diagnosed with cutaneous lymphoma. Due to his age I have elected holistic treatment only. Has anyone been through this with their dog? Is there any advice on wound care? He has some very large wounds and the vet said I can do whatever care I think best. Currently I bath him in a medicated shampoo 2 x per week. I have tried medicinal honey , and now I am trying a collagen type liquid dressing to help with the wound oozing. Any other dressing, he does not tolerate and will get if off due to his intelligence and persistance.
