The ear is made up of three part:-

The Pinna (plural Pinnae). The outer part of the Exness ear (the flap) which collects and funnels sound to the ear drum. The ear drum is a white sheet of tissue, stretched across the ear canal. It changes these sounds into vibrations.

The Middle Ear. This part of the ear contains the ear bones (ossicles). These transmit the vibrations from the ear drum to the inner ear.

The Inner Ear. This is where the vibrations are translated into electrical signals. These signals are then transmitted to the brain, which interprets them into sounds.

Any of these three parts can, and often do, cause problems in dogs. Groomers should check every dogs’ ears, every time they come into the salon. It only takes minutes to do and can save a lot of discomfort for the dog and for the client, as the cost of treatment from their Vet will be less.

The ears can be kept in good condition by cleaning with cotton wool. You should only clean the outer part of the ear that you can see. Do not use cotton wool in the ear canal itself. This can act like a plunger, forcing wax further down the ear. A foreign body, such as a grass seed, can become lodged in the ear. This should only be removed if it is visible. A Vet should be consulted if you suspect that anything is lodged inside the ear canal.

The first sign of problems with the ear is a bad odour or brownish discharge. If the ear flaps are ulcerated or the dog shakes its ears, advise the client to see their Vet as soon as possible.

There are many Exness Indonesia causes of ear infections but one of the most important causes is lack of ventilation. This is commonly seen in the hairy breeds, such as Spaniels, Setters, Old English, etc, in which the ear pinna is folded tightly against the head. Some breeds have very narrow ear canals, which leads to poor ventilation and in some cases, ulceration of the folds.

Breeds such as the Poodle, Bichon, Lhasa and Terriers have hair growing inside the ears. The hair needs to be pulled out periodically, either with your fingers or tweezers. If this is not done, wax and dirt cling to the hair, clogging up the ears and preventing air getting inside and therefore causing infection. Smooth coated and pricked ear breeds seldom suffer from ear problems. Many dogs with ear infections also have a concurrent skin infection.

EAR PROBLEMS

Aural Haematoma

A blood blister of the ear flap. You will see this problem mostly on dogs with large ears, such as Spaniels, Poodles, Setters, etc. However, any breed of dog can suffer from Aural Haematomas.

Symptoms – A lump under the skin of the pinna.

Underlying causes – A dog scratching its ear or shaking his head, in response to irritations such as fleas, mites or ear infection. If the dog scratches too hard, bangs the ear against a solid object or shakes it too vigorously a haematoma can occur. There are also some suggestions that an aural haematoma may be caused by the dog’s immune system reacting to infection and causing an accumulation of fluid around the cartilage sheet.

Treatment – Veterinary attention must be sought. The haematoma may only require draining with a syringe or the ear flap may need to be cut open to enable the Vet to flush out all the contents of the haematoma. Antibiotics and painkillers are usually prescribed. Arnica, a homeopathic treatment will help reduce blood loss and tissue damage and Hamamelis (witch hazel) will help relieve pain.

Ear Flap Wounds

Symptoms – It is very likely that any ear wound, minor or serious, will bleed a great deal. Even if the actual wound itself does not cause the dog any real pain, the irritation of blood running down the ear is likely to cause him to scratch the ear or shake his head.

Underlying causes – The ear flap may be bitten or scratched during a dog fight. Damage may be done when grooming a matted ear, especially if a brush is used too hard at the tips of the ear flap. Barbed wire or jaggy plants such as brambles can also cause damage to the ear.

Treatment – Clean the wound with exness.my.id an antiseptic solution such as saline (one tablespoon of salt in 0.5 litre of warm water). Once this is done it will be possible to see the extent of the injury. If this is significant, then veterinary attention should be sought as the wound may require stitching. If a minor wound, that has been cleaned thoroughly and treated with antiseptic cream or powder, still looks inflamed after a couple of days, then veterinary treatment should be sought, as the dog may require antibiotics.

To keep an injured ear flap in place, cut one leg from a pair of tights. Put some padding, such as gauze, around the affected area. Place the leg of the tights over the dog’s head in such a way that the ear is held flat against the side of the dog’s head. Failing this, a carefully wound bandage can be used to hold the ear flap against the dog’s head.
