in Germany we only have about 600 puppies born per year, as such we have been very fortunate to be lesser affected than other countries with SM, and have the benefit of learning from suffers elsewhere.
The general level of knowledge amongst Cavalier owners in Germany regarding SM is very little (I count myself amongst those people).
There is currently an argument goin on between the three major clubs in Germany about how to combat SM. Two of the clubs have decided to mark the pedigree certificates of certain dogs who have had offspring which are "neuroligically suspicious" i.e. supposedly have SM. The other club is against this as they claim that there is not enough scientific evidence to support stigmatising the dogs in this way.
As we are a bit backward regarding SM - I would love to hear the opinions of the users of this forum on this matter.
