Finn has been shedding since December. Not blowing coat but clumps of fur which is not normal for him. He does not have any bald spots or anything just lots of fur clumps. He is also throwing up alot. We went through this last year with an belly making all sorts of noises and throwing up bile almost every night, went to the vet and they found nothing. We have been fighting the same for the past month but now he throws up his food including rice and chicken that we have given him to calm his belly. Any thoughts as to what is going on?
