If your kd dog is suffering from nausea and not eating because of it, try asking your vet for Mirtazipine. This can help - and in some cases - it can be nothing less than a miracle cure for this symptom. It actually provides three different treatments all in one medication - treating nausea, inappetence/refusal to eat and anxiety/depression. Like many drugs, it's clearance from the body is through the liver and kidneys, so the normal dosage should be reduced by 30% to help prevent any stress on these organs.
