Cavaliers are generally low-maintenance. Combing or brushing routines 3-4 times weekly, plus some occasional baths when necessary, are already enough. If your Cavalier often plays outside and then spends time on the bed (and other furniture inside), bathing should be done at least once a week.
Cavaliers with feathered hairs on their legs and ears are at risk of tangling their hair. You should check these areas more often so mats can be combed out. Trim their hair between their paw pads and clean their ears regularly. Overall, the most challenging task you may encounter is keeping their white paws flawless.
As average shedders, Cavaliers don't require special clipping/trimming routines. It's even better to keep their natural feathering hairs, especially if you like to maintain their furry-footed, hobbit-like appearance. However, some prefer trimming their dogs' feet to give them a neater look.
Any skin and/or hair coat issue exhibited by your pet should warrant an appointment with your pet clinic Tampa, FL
