he was at the vet a couple of weeks ago for routine annual health check. All fine, except ongoing thyroid problem for which he is on meds.
But suddenly he appears not to be able to hear. If he is asleep on the sofa, he wakes up and appears disorientated and wobbly but within seconds seems okay again and is walking normally.
Any ideas? He suddenly seems to have aged and I don't know what is normal in the ageing process and what is not. Not sure if I'm worrying unnecessarily.
