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 dog 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.
Any condition that blocks light from getting to the retina impairs a dog’s vision. Corneal diseases and cataracts fall into this category. Glaucoma, uveitis, and retinal diseases are other important causes of blindness in dogs.
Most causes of blindness will not be evident on general observation of the eye itself. But there are some signs that suggest a dog may not be seeing as well as before. For example, a visually impaired dog may step high or with great caution, tread on objects that normally...
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.
In his bestselling book, The Intelligence of Dogs, neuropsychologist Stanley Coren, PhD, focuses on trainability as a marker of intelligence.
The University of British Columbia psychology professor relied on the assessments of 110 breeds by more than 200 professional dog obedience judges who scored breeds based on working/obedience tests.
The top dogs absorbed commands in less than five repetitions and obeyed them 95% of the time or better. Here's the list along with a breed description by the American Kennel Club:
1. Border Collie: A workaholic, this breed is the world's premier sheep herder, prized for its intelligence, extraordinary instinct, and working ability.
2. Poodle: Exceptionally smart and active. Bred to retrieve things from the water. The miniature variety may have been used for truffle hunting.
3. German Shepherd: The world's leading police, guard, and military dog -- and a loving family companion and herder.
