Went to the health desk at Crufts yesterday, which was highlighting the various BVA/KC schemes. They've produced good and comprehensive A4 four-page information sheets for them, and the CM/SM one includes a list of all the new grades and a list of which grade dog at which age can be mated to which other grade of dog. For those of you who haven't met them, the grades are as follows:
Chiari Malformation:
Grade 0 No Chiari malformation
Grade 1 Cerebellum indented (not rounded)
Grade 2 Cerebellum impacted into, or herniated through the opening at the rear of the skull (the foramen magnum).
Syringomyelia
Grade 0 Normal (no central canal dilation, no presyrinx, no syrinx)
Grade 1 Central canal dilation less than 2mm in diameter
Grade 2 Syringomyelia (central canal dilation which as an internal diameter of 2mm or greater), or separate syrinx, or pre-syrinx with or without central canal dilation.
The grade is qualified with a letter indicating the age group at the time of scanning as follows: a = more than 5 years of age; b = three to five years of age; c = one to three years of age. As SM is a progressive disease the grade is not valid without the qualifying letter.
The leaflet also has pictures of scans showing what the different grades look like. I thought it was a very good leaflet, with lots of other information for people wanting to scan.
