I think it depends on the dog rather than the sex! I have a male and a female. both are very loving and wouldn't change them for the world!

If you cant decide, I think maybe you should phone a professional Cavalier breeder and ask if they have a litter on the way and when they are born go and have a look at them and see which one you think would suit you.

A friend of mine a couple of years ago did this and was intending to get a female, but after visiting the pups, she decided to go for a male.

Hope this helps
