Bichon Frisé
The Bichon Frisé is usually a joyful little character – very small, with an abundance of fur that needs daily attention. Breed experts say that the Bichon’s fur needs to be combed thoroughly on a daily basis. Light brushing is not enough and will result in matting. A prospective owner needs to be prepared to carry out this task on a daily basis.
In a 2004 UK Kennel Club survey, the leading causes of Bichon Frisé death were old age (23.5%) and cancer (21%). In a 2007 USA/Canada breeders survey, the leading causes of death were cancer (22%), unknown causes (14%), hematologic (11%), and old age (10%). Hematologic causes of death were divided between autoimmune hemolytic anemia (AIHA) and immune-mediated thrombocytopenia (ITP). AIHA and ITP were responsible for the greatest amount of Bichon Frisé “years lost.” “Years lost” is a measure of the extent to which a condition kills members of a breed prematurely. While cancer is a more common cause of death than AIHA/ITP, Bichon Frisés that died of cancer died at a median age of 12.5 years. Hematologic deaths occurred at a median age of only 5 years. Bichon Frisés in the UK survey had a lower rate of hematologic deaths (3%) than in the USA/Canada survey (11%).
Bichon Frisé’s are also prone to liver shunts. These often go undetected until later in life, leading to complications that cannot be fixed, and therefore liver failure. Bichons who are underweight, runts of the litter, or have negative reactions to food high in protein are likely to be suffering from a shunt. When detected early, shunt often can be corrected through surgery. However, the later in life the shunt is detected, the lower the likelihood of surgery being a success. Shunts can be kept under control through special diets of low protein and through medications to support liver function, help flush toxins that build up in the kidneys and liver, and control seizures that often occur as a symptom of the shunt. Without surgery, Bichons with shunts on average live to be 4–6 years old. Owners of a smaller than average size Bichon must consult a vet. Other symptoms include dark urine, lethargy, loss of appetite, increase in drinking. Seizures come in all forms; episodes of seizures can begin early on but go undetected. Early seizures can appear to be the Bichon in a hypnotic state (staring at something not there), or to be experiencing an episode of vertigo, or being drunk. Shunts are a serious condition of smaller breeds, and often not associated with Bichons.
AIHA and ITP
Because autoimmune hemolytic anemia (AIHA, also called immune-mediated hemolytic anemia, or IMHA) and immune-mediated thrombocytopenia (ITP) are responsible for premature Bichon Frisé deaths, Bichon Frisé owners should be particularly alert to the symptoms of these conditions. In AIHA, the dog’s immune system attacks its own red blood cells, leading to severe, life-threatening anaemia. Symptoms include weakness, loss of energy, lack of appetite, vomiting, diarrhoea, rapid heart rate, rapid breathing, dark urine, and pale or yellow gums. Thrombocytopenia often accompanies AIHA. In ITP, blood platelets (which cause blood clotting) are destroyed. The most common clinical signs are haemorrhages of the skin and mucus membranes. Owners of Bichon Frisés showing suspicious symptoms should seek immediate veterinary care as these diseases can strike with little or no warning and kill very quickly. Mortality rates of 20% to 80% are reported.
