Another incident

Flash went for a rottie this morning, again totally unprovoked! Flash was off lead (which was my fault, I should have kept him on lead until I was fully around the corner like I normally do), walked up to the dog and went for him. As always, Flash was of course muzzled so no damage done, but this is not good. I can't wait to get him checked at Fitzpatrick's and if that shows nothing significant, then I will get Mark to do full blood works and a comprehensive thyroid test... In fact, I will probably get that done either way. Something is wrong with Flash and I need to find out what it is!
