I've had Chesapeakes since 1981 and when someone asks me if they should get a Lab or a Ches., I usually suggest they go with the Lab, because people that get Chesapeakes, almost always know without asking, that's what they want. If there's any question in your mind, go with the Lab--there is a reason they're so universally popular. Chesapeakes aren't right for everyone.

What I tell people who ask about aggression in Chesapeakes might answer your question. Chesapeakes never attained any great popularity as pets, and were never bred to be easy, one-size-fits-all love everyone dogs, unlike Labs and Goldens. So they tend to be more primitive and instinctual--and they are far more territorial than other retrievers. Territoriality is not the same as aggression, though if not addressed early and often with plenty of socialization, structure and training it can easily beget aggressive behavior. This is not a breed that does well loose in a fenced backyard in suburbia.
Rather than repeating the good stuff that's already been mentioned, re-read Bryan's post #24 (of course I think it's great since I'm the breeder of his Chesapeake ) and BHB's #45. If you really enjoy working with your dog on a daily basis, and you like an intelligent, problem-solving kind of dog, you might really enjoy a Chesapeake. But as already mentioned, the socialization is key--early and often. And again, if there is any question in your mind about which breed is right for you, then go with the Lab.
