You might think your beagle is the smartest canine on the block, but he's got the dubious honor of being among the least trainable of breeds. The snarling Doberman next door? He's a quick study.
Dog intelligence, like human intelligence, comes in various forms. And although the best in any breed can be nurtured by owners willing to put in the time and effort, there are fixed realities when it comes to your animal's inherent qualities.
If it's bred to hunt, herd, or retrieve, the dog is more likely to be quick on its feet, eager to work, to move, and to please you. It will learn faster. If it's bred to be a livestock guard dog or a scent hound, it may seem distracted and just a bit dense.
Yet, even if some breeds are more nimble, trainers say any dog can learn the basics like sitting and staying. It just might take them longer to catch on.
The key is knowing what your pooch is built for and how to motivate him.
But keep in mind that the smartest dogs often don't make the best pets. Your job is to find a breed that suits your lifestyle and to focus on bringing out the best in your dog.
