Border Collie Los Baganes
All dog breeds have hereditary genetic illnesses, and the Border Collie is no exception.
Before we continue, please do not worry! The below is simply information for you to read at your leisure. Needless to say that, as breeders, our aim is to avoid these illnesses cropping up in our puppies.
This arises as a result of the malformation of the dog’s hip joints that do not fit perfectly in the acetabulum (the hip socket in other, slightly more intelligible, terms). Studies indicate that this problem is hereditary in 70% of cases and environmental in approximately 30%. When it comes to the Border Collie, environmental factors include its diet and an excess of food supplements, together with games of a more violent nature when the dog is in its infancy. In order to minimise the risk of your dog suffering from this, it is recommended that Border Collies are not made to work until they are at least a year old.
-Collie Eye Anomaly (CEA):
This illness affects the correct formation of the eye in Sheep Dogs. When the Border Collie suffers from this illness, it is somewhat similar to that suffer by Rough and Smooth Collies - it appears to be passed down as an autosomal recessive trait (in other words, both copies of the genes in each cell have mutations). In the worst case scenario, this leads to blindness, preceded by leakages and retinal hemorrhages.
-Progressive Retinal Atrophy (PRA):
This is a hereditary illness that leads to blindness; it occurs in the majority of thoroughbreds. Early signs of this illness include nocturnal blindness, an inability to adjust vision when there is little light and, finally, the failure of diurnal vision. The rods and cones are affected first of all before finally leading to complete blindness. If a Border Collie is to suffer from PRA, it will tend to do so when it is aged two or older.
-Neuronal Ceroid Lipofuscinosis (NCL):
This hereditary disease is characterised by abnormal behaviour, blindness and forgetfulness: it can be described as the atrophying of the brain accompanied by the accumulation of ceroids (a yellow to brown substance) in the nervous tissues.
