Being relatively new to dog ownership, I've often wondered if I'm giving my dog enough physical exercise. I am trying to get my dog anywhere from 1 - 3 hours of exercise a day (depending on my commitments) and I'm wondering if any exercise at all is good, or maybe is one type of exercise (e.g.: high intesity) better than another. I'm sure it varies breed to breed. I have a ~45lbs female standard poodle who - if given the opportunity - would play fetch till she passed out. I work a 9 to 5 and now and then mornings or lunches are cramped for time, so I find myself in the back yard playing 15-20 minutes of fetch rather than the long walk I'd like to do. However, after a short bout of fetch she is panting and working hard whereas after a walk doesn't seem fazed at all and looks like she's ready for a good bout of fetch! ...in the end I want to do what's best for my dog. Thanks!
