There of course no such breed as a"Cavachon",these dogs are crossbreeds one parent being a Cavalier King Charles Spaniel & the other a Bichon Frise.
Cavaliers should have a full panel of
DNA tests, clinical eye(via a BVA panellist)/heart(Via a Doppler test done by a Cardiologist)/MRI scanned for Syringomyelia and the Chiari Malformation(assessed by a BVA panellist), plus hip/elbow/patella tested
The Bichon Frise should have DNA testing & clinical tests done, for Clinical- eyes Hereditary Cataract/DNA-Degenerative Myelopathy (DM)
Chondrodystrophy (Type 1 IVDD)/ Clinical-Hip scored/BAER hearing tested & possibly the following:-
Atopic dermatitis
Sarcoptic mange
Diabetes mellitus
Hyperadrenocorticism
Congenital portosystemic shunt
Immune mediated haemolytic anaemia
Cranial cruciate ligament disease (CCL)
Patellar luxation
Cataract
Urolithiasis
Primary ciliary dyskinesia
Then you have the mix of the two coats which means that they need a lot of grooming & regular clipping/scissoring to keep it under control.
TBH I doubt you will find any breeders of this cross do 1 or any of the testing, as they breed for money on the whole
