Regardless of their age, size or breed, the best canine fitness partners are interested in pleasing you, they're friendly with other dogs and humans, they're emotionally calm and centered, they're reasonably quiet, and they're non-aggressive. Since this list fits the vast majority of dogs, it leaves you lots of room for making a great choice.
If your new dog's primary job is to act as your fitness partner, you will want to select a dog that has been bred to enjoy being with people. Some breeds, such as the independent-thinking hounds, do not care all that much about humans and will be more difficult to train. When was the last time you saw a coonhound or Saluki leading a blind person across the street? That doesn't mean they can't be trained, but they do take more patience.
Companion dogs of all kinds, and many working breeds, have been bred for their trainability. Do careful research about the type of dog you are considering, to make sure their needs and abilities will match your own.
If your new dog's job is to help you bring yourself out of a state of
lethargy or depression, or if you're just plain lonely, you may be drawn
to a happy, energetic canine who wants to play, or perhaps you'll prefer
an abandoned mutt who clearly needs your care and affection. Definitely
look for a dog who will love being with you. Some dogs have empathy, and
some dogs, (like some humans), don't.
Choosing between a puppy and an older dog.
Puppies have the advantage of being cute and endearing, and if you choose a breed that fits your personality and lifestyle it will grow up to be a great walking companion. As soon as your puppy has been vaccinated, he can start his daily walking routine. Young puppies can't go very far, of course, but you can increase the distance you walk as he gets older. Remember to reinforce the rules and treat him with quiet respect and dignity, and he'll be a loyal companion for many years. A great puppy personality test is available online, courtesy of Rolan Tripp, DVM . There are also a number of excellent books on dog breeds and behavior. I suggest that you do some research and talk to owners of various breeds, before choosing the pup or dog that's right for you.
A good breeder will be able to help you choose the best pup from a litter, if you let her know what you're looking for, what activity level you can give your dog, and a bit about your own personality and temperament.
You can find wonderful older dogs at the local Humane Society, through specific-breed rescue organizations, and through breeders.
Many breeders have "left over" pups that have gone beyond the cute stage but which have had lots of time to become well socialized with other dogs. Your local breeder may also have older breeding stock that has reached retirement age, and these dogs often make good pets. Make sure, though, that the older dog you get from a breeder has not spent his life in a kennel - it is difficult to toilet train a dog that has grown up soiling his own bedroom.
Rescue organizations usually foster their dogs, so their foster family
will have a very good understanding of the dog's temperament and any special
needs it may have. You may be required to fill out a lengthy questionnaire
and allow a home visit before the organization will approve your application.
Humane Societies and animal shelters usually temperament-test their
dogs, and will give you important advice to help you choose the
best dog for your household.
The most important thing to remember when choosing either a puppy or an adult dog is to match your own temperament and physical ability with that of your new dog. For instance, someone who enjoys many hours of blissful silence will not be comfortable sharing a home with a dedicated yapper. A human who enjoys spending time in enthusiastic athletic pursuits will be unhappy with a dog that prefers to spend his afternoons on the couch. If you want to cuddle, you won't want an Afghan hound.
If you're an older person with some physical limitations, you might want to consider an older pooch or a small dog. You can probably find a "used" dog at the local Humane Society who needs your companionship in his or her golden years. Most older dogs will not be disappointed if you can't walk as far or as long as you could 30 years ago, and they truly appreciate the love and care you give them. Even if you fondly remember the bond you had with a loyal, exuberant Labrador back in your teens, you should carefully evaluate your current situation so you can find the best match for the energy and personality you have now.
Don't assume, however, that an older dog will automatically be a slow dog - I know a 9 year old Border collie who could fetch tennis balls until my arm drops off, and I'm sure she'll be going just as strong when she's 15. Fortunately, she lives with someone who enjoys throwing tennis balls and Frisbees just as much as she does.
Since dogs come in many sizes and shapes, and they've been bred for different activities and temperaments, you'll want to carefully choose a puppy or shelter dog that you can easily relate to. Be sure you don't get a puppy or dog just because you like the looks of his breed, or because he's so cute, or because someone blackmails you with a threat to take him to the pound if you don't adopt him now.
This is an important decision that could affect the next 12 to 18 years
of your life, so choose wisely.
Marty Becker, DVM, the author of The
Healing Power of Pets, gives some excellent advice
for choosing an older dog from a shelter. I'll paraphrase his suggestions
here, but I strongly suggest that you read the full chapter in his
book if you get the opportunity.
Whether you choose a puppy or a "used dog" from the pound, you should always choose a dog that is less assertive than you are. Both humans and dogs have hormone levels that place them in a specific natural role in the pack (or tribe), and it is almost impossible to change it. Unless you really want to spend the next 12 years of your life fighting your dog for control of your household, you'll leave the macho, alpha pup or dog behind and find one more willing to follow your instruction and leadership.
That said, most dogs will happily seek direction and affection from their humans. After all, that's what they've been bred to do for thousands of years. The truly dominant dog that shows aggression towards its owner is either badly bred or a genetic mistake. Don't let anyone tell you there are no bad dogs. There are, just as there are bad humans. But they're rare. Humane Society shelters almost always test their dogs for any aggression problems, and these dogs are not put up for adoption.
If you decide to get an older dog from the local shelter, the staff will let you know if a dog needs a more experienced owner because of behavioral or health problems, and they'll counsel you away from any dog that seems to be a bad fit for your family. They'll know if a dog should not be introduced to a home that already has cats or other dogs, or if the dog can not be trusted around children. Be sure to pay close attention to their advice.
It is extremely important to also consider the dog's needs, and whether or not those needs can be met in your household. Some breeds, such as the Border collie, are often adopted by people drawn to the breed's intelligence and beauty, but who cannot possibly give the dog the full-time active job their muscles and minds require. Other people are drawn to the stronger breeds because they appear more macho, like the Rottwielers and pit bulls, or they go for the latest fad, like the Dalmatians that appeared in a Disney film.
Unfortunately, these wonderful, smart, playful and inventive dogs often
find themselves at the dog pound before their first birthday, because their
humans couldn't keep them working for 14 hours a day, or allow them to run
25 or 30 miles, as the dogs had been bred to do. To get an idea of what
types of dogs are most often mismatched with their humans, just take a trip
to your local dog pound. The same breeds show up over and over again, because
the average person doesn't have the right home for them.
On the other hand, if you spend lots of time at home and can give
one of these dogs the exercise and mental stimulation they need,
one of those overly-active pound puppies could be a perfect match
for you.
