Any gundog or working breed will be quite hyper as they were bred to run or hunt! CKC spaniels are nice dogs, although all the ones I have known were prone to weight gain and had heart and breathing difficulties in their twilight years.

I too recommend rescuing, perhaps for your first dog it would be best to find yourself a nice crossbreed. They are generally longer-lived than purebreds and come in a huge variety! When you see unwanted animals every week like I do and a few other people on these boards (such as Krista, I know she's a volunteer too ) you realise just how important rescuing is. Plus, you'll save yourself a lot of money by rescuing, pedigree pups can start from £600 and up, whereas you can get yourself a lab from a shelter for about £100.
