Dogs and cats can get ear mites - small white little creepy-crawlies that live in your pet's ears causing itching and infection. The technical name for them is Otodectes cynotis.
These ear mites are very infectious - if you have several pets and one pet is diagnosed with ear mites then all pets will have to be treated, otherwise it will just keep going around in circles.
It is not unusual at all to see puppies and kittens coming in with ear mites. A good breeder will have treated the mother initally so the pups or kittens don't get infected from her, but unfortunately not all breeders do what we would hope they should. Sad to say it but it is a sign of neglect on the breeder's part if your new pet was given to you with ear mites.
Thankfully it is quite easy to treat ear mites - but only medications that are availabe from the vets will work. Don't waste your time getting anything in the supermarket or even a pet store, you're wasting your money to be honest and your pet will not get better.
Have a look at the video below for more information and to see them moving around like they do in dog's and cat's ears.
