The sea squirt is a primitive animal that starts life swimming, then attaches itself to a rock where it stays put its entire life. What's interesting about this creature is that once it attaches itself to a permanent home, it absorbs its own brain, and lives the rest of its humdrum life without one.
Our brain requires movement in order to function and grow, and yet, somehow, we live in a world that requires humans to move very little. Dogs are no different in this respect, and they suffer greatly when we neglect to keep them moving. We know our canine companions need exercise, but it's difficult for us to, well, move.
Of course, many people go out on daily walks or runs with their dogs, hire dog walkers or go to dog parks. Unfortunately, many others hope a quick walk around the block with their dog will suffice, or they believe that their dog will exercise himself in the backyard.
As we humans gain weight, so do our dogs. It's a good idea to become familiar with how your dog should look when healthy so that you can monitor his weight and keep him looking and feeling that way.
From above, your dog should look like he has a waist between his rib cage and his hips. From the side, most breeds have what's called a "tuck up" behind the ribs. If you have a long-coated dog, you might need to feel the waist to determine if this is the case. If your dog has neither, chances are he needs to lose a bit of weight (check with your vet to be sure).
Overweight dogs don't just eat too much - they exercise too little. And since most dogs love to exercise (unlike many of us), it should be easy to help them get and stay fit.
Not only do dogs need to exercise their muscles, they also need mental stimulation, without which they will become bored, restless and destructive, especially adolescent dogs and young adults.
There are very few dogs that actually exercise themselves in their backyard. Left to themselves, most dogs just hang out, waiting for you to appear. Walking your dog around the block for 15 minutes a day is not enough exercise for any dog, even tiny ones. Taking them for a couple of good hikes on the weekend is a good start, but they need exercise the other five days.
Dog walkers are just fine as long as they actually walk the dogs. Some are inclined to utilize dog parks, where some dogs exercise, and some don't. In fact, if you frequent dog parks, it's best to go after your dog has had his walk, so he can concentrate on appropriate play.
For people with anti-social, reactive or very fearful dogs, a treadmill is an option. There are treadmills made for dogs, but your dog can also use the one you have stored in the garage, gathering dust.
Optimally, adult dogs should get a couple of good outings a day - 45 minutes to an hour of brisk walking is sufficient. If you can walk your dog only once a day, try doing something different with him later in the day. Obedience training (works both brain and brawn) or playing games with your dog will help him get fit and settle nicely in the evening.
The important thing to remember is that just like you, your dog needs to get out and move.
Now if you'll excuse me, I think I'll go walk my dogs.
