Our family is looking to add a new member and my wife has taken a liking to the Cavalier King Charles Spaniel . Just doing some initial research seems like there are quite a few health issues . Any advice would be greatly appreciated . We are looking for a pet primarily and they seem to be pretty nice dogs .We recently lost our Norfolk Terrier due to heart issues and don't want to put my wife through anything that could possibly be avoided and realize there are no guarantees . just want to make an educated decision .
