I have notice with 2 of my yorkies get ear infection the vet says because the ears are not letting any air in then being down like cockerspaniels... they are to old to get them to stand up . so when i got my 3 new ones i took mustache clippers and took all the hair off and taped them up and they never get ear infection's.. plus in my opinion they look better and that is the way yorkie ears are suppose to be..
