Oh FFS, some of us are getting sick of this designer mongrel bollocks.
No, your friend should not buy one of these puppies, not if she cares about dogs. Cavachon is not a breed, it is a mongrel with clever sounding name. This means it was not bred by a breeder who cares about the breed, health checks the dogs before breeding from them, will literally go to the far corners of the earth to get the sperm from the best matched dog, follows the veterinary guidelines on number and frequency of litters etc etc.
It has been bred for money by a scumbag breeder who is nonetheless savvy enough to realise that if you breed two dogs from whom you can make an amusing name - cockerpoo, labradoodle, jackabee, cavachon etc, you'll always find someone stupid enough to buy one.
The breeding bitch has almost 99% certainly been kept in appalling conditions - just Google Images of 'puppy farms', show your friend and ask her if she honestly wants to support this industry.
Then tell her to either find a very very responsible breeder for a pedigree or better still, go to a rescue.
