All of these are excellent suggestions and would agree with them all. Most of us look for dogs with lineage that has high prey drive which equates to "hyperactivity". I'm patial to the Lab and the Brittany, but that is just my opinion. Be very careful with breeding of Labs and research the lineage carefully. Griffons and Chessies are another option.

Around here I have heard of a few people who have been buying crossbreads and having good success. The most popular are the Labradoodle (Labrador Retriever and Standard Poodle) and the Retrieverdoodle (Golden Retriever and Standard Poodle). The crossbreeding with the standard poodle helps tremendously with the shedding. I've also heard that the intelligence of the poodle improves the trainability of the dog. Some may frown on this crossbreeding, but for some I believe it is a valid alternative. There are obvious down sides as well. The prey drive isn't as sharp and the nose looses some of its intensity.
