The Cockalier's silky to wavy coat requires brushing three to four times per week to prevent matting, particularly behind the ears and in the feathering on the chest and legs. Professional grooming every six to eight weeks is strongly recommended to maintain coat length and health. The floppy ears inherited from both parent breeds are highly prone to moisture accumulation and ear infections — check and clean weekly. Trim nails monthly, brush teeth daily (or at minimum several times per week), and wipe any eye discharge regularly. The Cavalier King Charles Spaniel parent's cardiac monitoring needs should be an ongoing consideration.
