I just found out last week that Teddy has Grade 1 luxating patella and, having done extensive research, understand that there is no conclusive evidence that luxating patella is a genetic/hereditary condition. As a result, it is only a recommendation that dogs known to have the condition aren't bred. Additionally, the vet I spoke to advised that 90% of Yorkshire terriers, along with other toy breeds like the shih-Tzu and poodle, have the condition which does not always progress to surgery requirement. In fact, he and another university vet told me they would be more surprised if there was no luxating patella present. My dog was bred by a Crufts show breeder so it would appear it is an inherent issue as per vet advice.
I must confess that I have not read the whole issue here but I do know that my vet advised that there is no way to prevent the condition and there is no sure way to prevent progression and that surgery is not recommended unless and until the condition is debilitating to the quality of life which is normally only the case under extreme circumstances.
Hope that helps? |
