Thanks guys, I've passed them onto my boy.

Was in the emergency vets last night with him as he suddenly went absolutely frantic about his ears, had a head tilt, plundering round the house demolishing things in his frenzy
Still waiting on the biopsy results so he's got some ear drops to soothe the pain until they come through. I hope to God they shed some light on things, he can't go on much longer like this,

To top it off he's become very odd at times as well, freaking out about noises that he wouldn't usually notice, and it's really affecting how he is with us and the other dogs

Oh dear poor Bear and poor you , Lets hope they can get to the bottom of this soon.

What a worry for you - hope Bear is better soon.
