I know what it's like - pure biological warfare! My vet told me to give him 2-3 tablespoons yoghourt daily in his food and it helps. It took about 2 weeks to really make a difference but I'd recommend increase the dose and stick to it for at least 2 weeks. Still today Buddy lets every now and the go of one awful killer-dose, especially when he is in the car and gets excited, but other than that he is doing fine.
Good luck! But aren't they just loveable??
