The very least the parents should have is a current certificate(done with twelve months of the date you see it)& a current clear heart certificate & they should both be over 2 1/2 & perferably over 3 years of age. If the dogs are younger I would not touch the puppies
They should also both be MRI scanned for
Syringohydromyelia(SHM) if the parents are not scanned clear they I would require in writing a statement that there have been no cases of SHM on either side of the pedigree from the breeder. If they state their dogs have no lines to SHM dogs I'm afraid they are not telling the truth as every Cavalier in the UK has at least one line to either a carrier or an affected dog(it does not mean the parents have SHM or are carriers) & I would look elsewhere. If you look on my dogs website(via the link on my profile)you will see the breeding of my beautiful boy who has SHM(his father had SHM & his mother is a carrier BTW)& it is not puppy farm or pet breeding, but some of the top dogs in the UK. We are considering getting another Cavalier & have a possible breeder in mind who like us is aware & concerned about the total health of the breed
I personally would expect & prefer both parents to be hip scored for HD-but HD is not a particular problem in Cavaliers
I don't obviously wish to discuss any dogs other than my own & their pedigrees on the open forums
