My 14 year old chihuahua cross has an ongoing cough that is wearing him out. He's booked in on Tuesday to get X-rays of his throat and chest and in the meantime they have prescribed some cough mixture and metacam to relieve pain in his ribs from all that coughing. The poor thing, he only gets relief from the coughing when he's asleep. I am wondering if anyone could suggest something I could give him to soothe his throat in the meantime? He is diabetic so honey is a no no, so now I'm scratching my head.
