Cavoodles are pretty healthy dogs as long as you care for the Cavoodle properly and if possible take the Cavoodle to the vet for regular checkups to catch any health problems early on and treat them.
Some health problems that Cavoodles are prone too are Epilepsy, Hip dysplasia or luxating patellas, Eye Diseases that include cataracts and/or progressive retinal atrophy, Mitral valve disease and also Syringomyelia.
The Syringomyelia is a condition where the skull cavity is too small for the brain.
So those are the potential health problems that Cavoodles can have and are prone too but as long as you take good care of the Cavoodle or any other dog breed and feed them healthy, take them to the vet etc then the dogs should live a good long healthy life and may not have those health problems.
