hi all i`am new to the site and was wondering if any of you cavalier lovers have come across this problem we have with our 3 year old blenheim named fudge. when he gets excited he sometimes starts to make this noise like he is reaching to be sick as if something is stuck in his throat, also his whole body goes into a sort of spasm.this can last for around 5 minutes and is very stressful for fudge as he is very moody for a couple of days after.Is this common in cavaliers? any advice grateful thanks
