Hi Becky - I've got a cavalier king charles too, called Misty. It's a great breed, small but fun and very, very cuddly!! They are a bit talkative, and not too bright, but loveable and so very pretty. Misty is 3 now and she was very slow learning, but now she's fine and can even do tricks (sort of). I don't often take her on long walks (well sometimes it's just out in the garden) but she doesn't mind.
Many years ago, I used to have 3 springer spaniels - now they were hard work!! But I loved their energy and eagerness and was looking for something similar but not so demanding. Misty is a miniature springer but without the insatiable water and ball obsession. She's called a blenheim colour - that's chestnut and white.
Good searching - a dog is a great companion - Sylvia xx
