Well, there are some things to contemplate before taking the plunge.
If you intend on keeping your new furbaby inside, consider the consequences of shedding and/or known chewing breeds. Also, you need to find a dog that suits your lifestyle habits. Labs and huskies are big shedders and require a lot of grooming maintenance, in that respect. But, it can be done.
For example, are you an outdoorsy dude? Like to go camping, hiking, etc? Rather be outside than inside? If so, you may want to select a 'high energy' dog like the ones pictured in your post. Many hound, shepherd, spaniel and retriever breeds need lots of exercise to avoid 'bored habits, like chewing, digging in the trash and other naughtiness.
If you are a stay-at-home, couch potato-y person, you will want more of a calm, lap dog (manly man, of course) type - like a bulldog, dachshund, or shitzu perhaps? <--all still very studly and total chick magnets.
Unless you deal directly with a breeder, you will likely get a new friend with several breed traits - just like a new 'people' friend.
The best dogs I have ever had were shelter dogs - some were mixed, some were purebred. They have always been the most loyal, sweetest and grateful dogs. It's eerie in a way, almost as if they know that someone has given them a second chance at life.
Have you had a dog before or will this be your first?
