Cardiology: heart and my
is a dog with a naturally higher than normal heart size
Like all breeds, he may have heart defects but presents a predisposition to the persistence of the ductus arteriosus, a malformation that is surgically corrected with a good prognosis
Like many other small dogs, it is predisposed to mitral endocardiosis (degenerative disease of certain cerebral valves). ; ur). The disease occurs in middle-aged dogs and it is often the evidence of a heart murmur that makes it suspect.
Dermatology: skin and skin diseases
The alopecia of diluted dresses is caused by some genes that determine the color of the coat. Lesions are manifested by poor hair growth and irreversible hair loss.
In Yorkshire Terriers, the "leather ear disease" appears to be of genetic origin and affects dogs between 6 months and 3 years of age.
Endocrinology: Hormones and endocrine diseases
Yorkshire is predisposed to some forms of Cushing's disease, also known as hypercorticism. The disease particularly affects middle-aged or older animals and more often females (55 to 60%).
Gastroenterology: digestive diseases, intestine, stomach, liver, pancreas,...
Different predispositions are described in the breed. One of the most documented is the congenital portosystemic shunt, a malformation of certain vessels bringing blood from the digestive tract to the liver. It can lead to various neurological disorders, urinary,... A suitable diet and surgical correction can generally control the situation.
Nephrology-urology: urinary diseases, kidneys, bladder,...
Different types of urinary calculi are described in the breed, most commonly in middle-aged dogs
Neurology: Nervous diseases, brain and nerves
Hydrocephalus and Atlanto-axial subluxation are described. The first, in its congenital form, is quite common in Yorkshire. The first symptoms usually appear around 4-5 months but sometimes much later.
The atlanto-axial instabilities are related to a lack of conformation of the articulation between the first and the second cervical vertebra. They are responsible for nervous disorders that range from a simple neck pain to a paralysis of the four limbs. The treatment of choice is surgical
Ophthalmology: diseases of the eyes, eyelids,...
Numerous affections of the eye or its appendages are likely to reach Yorkshire, like a cataract, a keratoconjunctivitis sicca (also called "dry eye"), disorders of the retina,...
Orthopedics - Musculoskeletal System: Bone, Joint and Skeletal Diseases, Muscle Disorders
Three major orthopedic conditions are quite common:
& bull; Congenital dislocation of the elbow
& bull; Medial dislocation of the patella
& bull; Aseptic necrosis of the femoral head
They are often seen in relatively young dogs and the dominant symptom is lameness. An orthopedic examination and x-rays then make it possible to establish the diagnosis and choose the most appropriate treatment.
Diseases of the respiratory system
In Yorkshire terriers, tracheal collapse is a fairly frequent respiratory disease. It is most often seen in older dogs, but congenital forms are possible. There are several degrees. The most severe forms can be life-threatening. A number of severe cases can be managed by placing a tracheal stent. The condition is aggravated by obesity and is manifested by dry cough, noisy breathing and sometimes severe breathing difficulties.
The Yorkshire Terrier appears to be prone to cryptorchidism (abnormal testicular development) and like many small dogs at births sometimes delicate. > The medical content of this sheet was written with the kind collaboration of CHV Frégis. More information on the health of Yorkshire on the
