If the dog or can has a ear hematoma it has a bad ear infection causing the animal to shake an poping the blood vessil in the ear, if thats the case it needs surgery an ear treatment.
Make an appt
It could be from scratching the ear or possibly getting the ear caught in something
It is a broken blood vessel, make an appt., but the dogs ear will not stand up (if his or her ear is erect). I believe they do a shady job. Had 2 cats ears done, dont like how it looks. Also, harder to clean.
