I am quite shocked that after taking my pups at 20 months old to the vets because they were blind and going totally weird she never mentioned this when she could of taken bloods and had the DNA tested.
Having read up on collie blindness (perfect pups but started to deteriorate after 16 months old) Doing my own research I have unscientifically to come up with this Ceroid[/size][/color] Lipofuscinosis
[/size][/color]
[/size][/color]The [/size][/color]Affected animals appear normal until aged approximately 18 months. However, from the embryonic stage, there is a metabolic defect which allows a waste product 'ceroid lipofuscin' to accumulate in body cells.[/size][/color]The brain cells have very little room for waste products and symptoms emerge when an accumulation of waste begins to compress and destroy healthy brain cells. As a result, by 18 months of age some or all of the following signs may be noted:[/size][/color]Unreasonable apprehension or fear of familiar objects/surroundings, sight disturbance.[/color][/size][/color]Abnormal gait - is unsteady on feet, has difficulty with jumping or climbing or placing feet, tends to prop or goose-step.[/size][/color]Demented behaviour, mania, hyperactivity, rage.[/color][/size][/color]The disease progresses rapidly once the initial signs appear and the distressed animals have not been kept past the age of 2 1/2 years. Unfortunately there is no treatment for an affected animal.[/size][/color]To date there is no test available to identify which dogs have inherited the disease or are carriers of the defective gene. Suspected cases can be confirmed by brain biopsy. A post mortem examination will give an accurate diagnosis.[/size]
This is exactly what my two pups had they changed from fun loving mad pups into a sad pathetic mess, terrified of people, stiff legs, slow and totally blind. The final step came when I ran over one as she didnt see me, one went missing and this one was appalling to see her - she couldnt gauge where I was and all night wondered back and for on the yard. I felt sick seeing her alive every day and I had to get her put out of her misery.[/font]
[/size]Lesson leant is to only buy from a registered breeder and will insist on replacing a working collie that they have a DNA test to check for any anomalies that apparently 90% of collies carry.
[/size]Sad end...
