hi
 
Just a couple of questions if you dont mind, i have tried searching but have not come across the answers to my question.. 
my Dog Ozzy an english bullterrier has just been diagnosed with a liver shunt he is two years old, i have been advised to feed him royal canin hepatic by the vet which is what i am now doing, previous to this i was feed him a natural diet of raw meat and vegetable..
for a long time now he has drank excessivley and urinated a lot..he often has a vacant look and is often shaking, very tired , eats dog poo???,and is very agressive to some dogs 
How many times a day should i be feeding him is small but often best, or does it not matter? 
also 
for the last 9 month he has has sores on both tips of his ears, they will not heal up, they scab over with a black bloody colour scab, the scab falls off and it then bleeds again, we have tried various creams from the vet but nothing helps, could the liver shunt be causing this? 
the vet has told me that they would not be able to operate on him as it would be a very risky operation because of his size ? 
will this cut his life short?
