Hello I need help please, I have a 10 year old male boxer who has developed a problem in the last few months, he is drinking a lot of water and he is urinating a lot, I have taken him to vets and they did tests on him and they have ruled out diabetes he was put on some antibiotics they have not worked so they put him on a stronger dose, again these have not worked, he is not in control when he urinates and quite frequently his bed is wet, is there anything I can try or does anyone else had this problem and found a cure, someone did tell me to try some herbal medicines for dogs, but I am not sure. Any help or advice will be great
