Most ear infections are not emergencies, but if the animal is distressed and you cannot stop them from scratching or shaking their ears, then they may cause significant further damage if the ear is left untreated. A buster collar may help if you have one to hand that fits well.
Occasionally, swelling of the ear flap may occur either from the damage caused by scratching and shaking, or from trauma, this is known as an aural haematoma. The swelling is caused by blood leaking into the space between the skin and the cartilage of the ear flap. Unless the animal is significantly distressed, these are usually okay to leave until the clinic reopens for routine work
These are difficult to give firm advice about over the phone. Minor eye infections will wait until the clinic is open – these are usually characterised by a creamy discharge and the eye being either partially shut, or covered partially by the third eyelid (a pale flap which arises from the nose side of the eye).
More significant eye problems, especially if there is pain and/or swelling will often require an emergency appointment. In case of doubt, please phone the duty vet to describe your pet’s symptoms.
Pets can itch for many different reasons – allergies, irritation from the environment etc. Most pets with itchy skin are not considered emergencies and an appointment can be made for when the surgery is next open. However if your pet is extremely distressed, they have broken the skin and there is bleeding or it is accompanied by any other signs you can contact the duty vet to discuss the problem.
