If the dog's ears are not cleaned, they will get ear mites and will not heal themselves, and they may be infected.
How did I find out that my dog got ear mites:
1. Scratching your ears all the time and shaking your head.
2. The ears smell bad and have a smell.
3. There is something black in the ear canal, which looks a little disgusting.
4. There are no unwilling tears, and there are no tears before.
The reason why it got ear mites was that I forgot to bring it ear drops home during the week of the New Year, and it didn't wash it, plus it played with the dogs in the village every day, and it was dirty.
My dog's ear canal is "L" shaped, with the child net of this ear drops is just right, first clamp it with the leg or it moves, and then along the ear canal put the ear drops into the drop 3 drops (my family seriously dropped 3 drops, generally drop 2 drops on the line), and then pinch the root of the ear has been rubbing, rubbed for a minute, in letting the dog throw out on the line, and cleaning the ear canal is similar.
Wash the dog's ears once a week, don't forget, don't forget to bring ear drops when you take it home or something!
