Coton De Tulear


The expected lifespan of a Coton De Tulear is 12 - 16 years, some even longer; therefore the health of your Coton should be important

There are still relatively few genetic health problems within the breed, and at present the UK Kennel club require no health testing, therefore a lot of breeders do not carry out health testing, But there are health tests available for the Cotons and most breeders in Europe carry out these as routine, as most Cotons in the UK derive from European lines, we feel it is important to
use the health tests where available 


Below is a table to help you understand how heriditary health problems are avoided 


CMR - Canine multi-focal retinopathy

Canine multifocal retinopathy (CMR) is a hereditary disease. 

CMR disease usually arises before 4th month of age in an affected puppy. Clinically, rose-grey coloured lesions are remarkable in retina. These lesions are of different size and shape and are occurred in both eyes of affected individual. Total blindness usually comes in higher age

Testing is done via DNA taken from the dog (blood or salava)

PH1 - Primary Hyperoxaluria type 1

Primary Hyperoxaluria (PH) is a rare autosomal recessive disorder It is characterized by the accumulation of oxalate and subsequent precipitation of calcium oxalate crystals, primarily in the kidneys, leading to progressive kidney failure the crystals are also accumulated in other tissues, for example in bones, joints, cartilages, retina and muscles

Symptoms are anything ranging from

Lack of appetite, Lack of energy,
Excessive urination, Excessive thirst, Weight loss, Vomiting, Abdominal
enlargement, Bloody urine, to Abdominal pain

There is no cure for this condition, most dogs die from kidney failure
by early adulthood

 BNAt-Bandera´s neonatal ataxia

Also known asneonatal ataxia or Bandera syndrome

Originally called Bandera´s syndrome after the first puppy of Coton de Tulear breed affected, in which the clinical signs of this disease were described.

Ataxia is a neurological symptom consisting of a lack of normal coordination of movements. In case of neonatal ataxia the lack of normal coordination becomes evident soon after birth.

 All affected pups showed similar clinical signs, they nurse well and grow adequately, but have difficulties from the time they become active, the affected pups are unable to stand or walk, despite their best efforts, they move uncordinatly all four limbs and these movements are often compared to "swimmer" movements, When attempting to move, they will frequently push themselves forward, but fall immediately to one side or the other in an attempt to get up, after they have fallen they continue to paddle their limbs.

Another common sign is a tremor or bobbing of the head, that are most dramatic when the pup is trying its hardest to hold its head steady, for example when the pup is trying to sniff an object and is referred to as an intention tremor, there may also be a tremor or jerking of the eyes

VMD - Type 1 - Von Welliebrand disease

Von Welliebrands disease is a blood disease, it can lead to excessive bleeding following surgery, trauma or spontaneous bleeding, due to the lack of clotting agent in the blood

Symptoms include, nosebleeds, blood in the urine or faeces, bleeding gums, excessive vaginal bleeding, prolonged bleeding after surgery or trauma 

There is no cure for this condition, it is managed on the basis of treat as it happens, but in worst cases it can lead to anaemia and death

PRA & Cataracts

Generalised Progressive Retinal Atrophy (GPRA) is an inherited eye disease in dog, this disease always leads to blindness. 

In all breeds of dogs you can observe the same features of the disease in affected dogs, affected dogs are night blind and there is a loss of the ability to adjust the vision to dim light, later as the disease progresses they have problems adjusting to daytime light and eventually complete blindness occurs. 

First signs are unsure behaviour in their normal environment, pupils of their eyes become dilated and the lens of the eye becomes cloudy and opaque, resulting in a cataract 

There are no DNA tests available for GPRA in Coton De Tulears, but we hope there will become one available in the near furute

In the meantime, there is an eye screening test available to check yearly for signs of the condition with the BVA 


A cataract is an opacity in the lens of a dogs eye, causing him to have blurry vision. If the cataract is small, it won’t likely disturb the dog’s vision too much, but cataracts must be monitored because the thicker and denser they become, the more likely it is they will lead to blindness

Cataracts can develop from disease, old age and trauma to the eye, but inherited conditions are the most common cause.

Signs are usually cloudiness of the eye, 

An untreated cataract may “luxate” or slip from the tissue that holds it in place, freeing it to float around in the eye where it may settle and block natural fluid drainage. This can lead to glaucoma, which can cause permanent blindness. Cataracts may also begin to dissolve after some time, causing deep, painful inflammation in the eye.

The only available test for Cataracts is the BVA yearly eye screening


Luxating patella

Luxating patella (or trick knee) is a condition in which the patella (kneecap) dislocates or moves out of its normal location

Patellar luxation is a common condition in dogs, particularly small and miniature breeds, not just our Cotons, the condition usually becomes evident between the ages of 4-6 months and always by 12 months 

Most cases of Patellar luxation are medial and this is frequently due to a congenital problem in toy and miniature breeds

The condition can be inherited through genetics; it is also caused by some forms of blunt trauma, obesity or over exercising of young dogs

Diagnosis is made through palpation of the knee, by a specialist vet to see if the knee cap slips inside the joint more than would normally be expected, it is a progressive disorder and can be debilitation if left untreated

 A surgical procedure is not always necessary in every individual with this condition, but where surgery is required the procedure is known as a trochlear modification, this procedure works well and they type performed depends on the individual case and clinician

The dog should respond quickly after surgery and is usually completely recovered within 30-60days, depending on the procedure, those that do require surgery will usually lead perfectly normal lives without restricted activity Luxated patella is categorised in four grades, depending on the severity of the condition:

Grade I: This is when the kneecap manually dislocates but goes back into place once the pressure is released. Considered as a mild case, with treatment not necessary, However, you need to keep a close eye on your dog in case the condition gets worse.

Grade II: The kneecap dislocates more often, either manually or automatically, when the joint is being flexed and continues to be dislocated until the joint is extended and the leg is turned into the opposite direction of the dislocation. Considered as the middle ground between mild and severe, dogs with
grades I and II should be closely monitored in case the condition gets worse.

Grade III: The kneecap dislocates on a regular basis, whenever the joint is flexed and extended. Dislocation is manually decreased when the joint is extended. This is considered to be severe enough to warrant surgery.

Grade IV: The kneecap is permanently dislocated and cannot manually be put back into place. This is because the groove is too shallow or, in some cases, completely missing. Surgery is needed to fix this problem

There is currently no DNA test to determin if Patella is genetic, so we have vet screening of our dogs from 1 year old
