When picking a breed, consider your own activity level and lifestyle, and think about whether you'll find a frisky, energetic dog invigorating or annoying. Dogs that like to chase need to be leashed or kept in a fenced area when outdoors, and you'll need a high, secure fence in your yard. Crate training is a wonderful way to prevent destructive behavior and housetraining accidents, but it won't work without the accompanying physical exercise and mental stimulation. The Pointer is an active, intelligent dog who needs daily exercise and stimulation. Because these signs are vague and can be mistaken for other conditions, it's easy to miss this disease as a diagnosis until it reaches more advanced stages. Keep your Pointer's physique sleek by measuring his food and feeding him twice a day rather than leaving food out all the time. Anything whizzing by — cats, squirrels, perhaps even cars — can trigger that instinct.
