Hello and welcome Angela

I am pleased Fudge has settled well. Sorry to hear he isn't keen on other dogs, could you give more information, is it all dogs, is he on the lead or off the lead, what does he actually do. How old is he, has he been neutered, do you know anything about his past.
John may help with this one (hopefully he sees it) so if you can give as much information as possible this helps set the scene.
I hope he is ok after collapsing, must have given you quite a scare.
