If someone is an inexperienced dog trainer, then no, it doesn't make any sense to get a puppy or a 1-yr old dog. When people look at a friend's 5-yr old dog who is well-behaved, they think “I'd like a dog like that.” So they go out and get a puppy of the same breed. But they don't realize a 5-yr old dog has had 5 years of socialization and training and maturation. It's like the difference between a 30-yr old adult, well-behaved human, and a 2-yr old child. If you don't have the time, patience, knowledge, skills, and ability to properly train, exercise, and socialize a puppy, then people really shouldn't get puppies. Get an older dog who is already socialized, mature, and has burned off all that puppy energy and stupidity.

As for large dogs needing a more firm hand, etc. That's really a misconception. Small dogs are far more misbehaved than large dogs. The reason is because people who own a large dog recognize that an out-of-control large dog can do a lot of damage, so they tend to correct bad behaviors at a young age (such as jumping up on people, barking, snarling, growling, and even biting). People who own small dogs think it is cute when a tiny dog growls or snarls at anyone or anything, so they laugh and inadvertently reward the dog by using a tone of voice that implies approval, and saying things like “It's ok Fido” or “Aren't you a tough doggy!” Then they laugh, giggle, pet and cuddle the dog, hug the dog, etc. All these things tell the dog it is doing a good thing and the owner approves of that behavior.

What they should be saying, in the same stern voice they would use on a large dog, is “Fido No!” And then let the dog know, through leadership, that they are not to behave that way.

Just watch at a Vet's waiting room sometime, the difference in behavior of small dogs (and how their owners react to that bad behavior) vs. large dogs.

Ultimately, an out-of-control large dog can do more damage, but it is no more acceptable for a small dog to be coddled and allowed to behave poorly. And incidentally, there are more dog bites in this country from small dogs than from large dogs. It's just the amount of damage from a small dog bite is not generally as severe.

I agree with you that small dogs can be more vicious and badly trained. however, I still do think that getting an adult dog as opposed to a puppy is a more difficult task. I was inexperienced when I got a puppy but I read up on things and dog behavior etc. and while our dog isn’t the perfect one, she obeys commands, is good with children, knows how to stand down etc. A 5-year old dog has already been “imprinted” on someone imho. That’s not to say it’s impossible, but for an inexperienced family isn’t a puppy better? And that of an easier breed?
