Hi, my Dutch Shepherd Roxy had 2 ear hematomas 1 in each ear last Friday, it is now Wednesday, and she is violently shaking her head again. Our vet did the quilted stitching pattern on both ears. She did not have an infection nor mites. She did it to herself from scratching a scratch which made more scratches which made them itch more. My question is, how do I prevent her from shaking her head while she is in a cone and still has her stitches in?
