Sorry to hear your dog is unwell.
The last post gave you some good advice.
The best you can do is focus on nutrition - it can do good and will do no harm.
Good fresh food, lots of filtered water, and nutritional supplements
You need vitamins and antioxidants, flax seed oil.
There is a lot of information on the internet about natural remedies for pets (just like for humans). I am a firm believer in this, and have seen some great results.
Let me know if you would like more details and I would be happy to provide information for you
All the best
Janet
