Thank you for your email. After your initial consultation we kept Willow under observation on 10th during the day. He was lethargic and refusing to eat but otherwise no real problem. However at about 5.40p.m. that day he broke into a severe bout of coughing and hacking which was quite worrying.
Taking your advice I rang our local verterinary surgery and we took Willow straight there. The vet examined him and gave him an injection of antibiotics. Willow had a slight temperature. The vet also suggested that he was possible constipated and therefore prescribed some Laxapet paste whuch we have given to Willow. The vet stated that Willow should recover fully by 12th but should he not we should return to the surgery.
I am happy to say that Willow appears to have made a full recovery after sleeping quite a bit on 11th. This morning, 13th he seems his normal self and is eating everything, probably making up for what he has missed.
Thank you once again for your assistance. The information you gave us on the night of 9th really helped us to understand Willow's problem and put our minds at rest.
