yes but i think the chari malformation and show up once the dog is fully grown, like harley has he is 3, without a malformation you cant get sm. di
Does the size of the cavalier play a role in the possiblilty of them having SM? Lucy is a larger cav and Tanner is on the small side.
I think it depends of where the gene of the dog originated from.
Ive read that a larger spaniel and a flat nosed type toy dog were used to create a new breed (cav king charles) if the gene that predeposes the brain is from the spaniel and the gene that predeposes the skull from the toy dog, then you have a brain that too big for the skull size or shape. This creates the chari-malformation. I dont know if some cavs, have genes from only the spaniels making them a larger cav, or the smaller toy dog making them a more petite cav, there is certainly a wide variety is sizes of cavs. Its certainly an interesting concept. di
