My Dog Has Alot Of Black Waxy Stuff In Her Ear. She Eats Well, Drinks, And Plays. Any Ideas?

Wax in ears is normal.this keeps debris and other stuff out. Dogs may appear to have more but this whoud be normal, just wash outside of ears and do not go further

I would just take her to the vet to check it out

Some amount of wax is normal, but excessive dark wax can be a sign of ear mites or early ear infection.  Other signs include ear irritation which may present as head shaking, scratching at the ears or rubbing the ears on the ground, redness, discharge and foul smelling ears.  Your vet can examine your dogs ears with an otoscope and do some ear swabs.  This will detect the presence of mites or a bacterial or fungal infection.  If it is mites, your vet can provide you with some medication, there are several options available.  Mites survive on your dog's coat so it is necessary to treat the entire animal, not just the ears.  In addition, ear mites are very contagious and it is necessary to treat all animals in the household.
