Thanks all. Some really useful insights. I will read all the links. Thank you
*@veterinari* Having slept on it, I am inclined to agree that them bounding in, later than they normally would, probably startled him. He has many beds where he can go and take himself. Funnily enough, we have noticed that in the evenings when it is just me and DH, he sits on the sofa with us for a while, then seems to get the hump and take himself off to a different sofa or his bed. So I think he must be grouchy in the evening like others have said.
I think his ear was hurting quite a lot yesterday, as when we took his coat off after his walk, he had a right old whinge (typical sight hound drama whineging). He did growl first and I don’t think his snap made contact, so I need to talk to them about backing straight off if he growls again. He is very good at asking for fuss if he wants it, so I will talk to the girls about this also.
His ear is a nightmare. We have tried so many things, he now won’t let us go near him to put drops in. He has had loads of different drops and washes, stinky stuff, steroid injections, it has been washed out, analysed. He does seem to have been better on his new diet, but his ear was full of gunk yesterday. I am not sure whether his system is sorting itself out. I removed the stuff I could see around the flap. I suspect this must have made it sore so I am going to leave it well alone.
Thanks once again all for taking the time to reply.
