EAR MITES IN DOGS
If your dog is uneasy with ears and you have noticed coffee ground like debris in one or both ears which keep on increasing that may be ear mites! Ear mites with scientific name Otodectes cynotis are tiny white, freely moving mites with two pairs of legs. These mites feed on tissue fluid and epidermal debris in the ear canal of dog. These mites may also be found in other areas of the body like neck, rump, and tail.
Otodectes cynotis have a life cycle of 3 weeks and can live up to 2 months in the environment. They mostly spread through contact but evidence suggests that fleas can also transmit them. These are highly contagious mites and spread very fast if more than one dog or cat is present in-house.
Otodectes cynotis cause severe irritation to the skin of ear canal and cause secretion of thick reddish brown exudates which form crusts. This is a very uncomfortable condition for dogs. The owner often notices in the dog the following symptoms.
- Regular ear shaking.
- Scratching of the ear.
- Coffee ground like debris in the ear
- Inflammation of ear canal.
- Reddish brown crusts
Diagnosis: a Direct microscopic examination of ear debris suspended in mineral oil.
Caution: Don’t treat at home consult your veterinarian for any treatment of your dog.
Antiparasitic agents are used to treating mites. Ivermectin weekly once for 3-4 weeks is found to be effective. Fipronil spot-on is very effective in ear mites infection. A single application of Selamectin is found to be effective in 98% of dogs.
