I concur about Labs and mouthiness, but then again they’re RETRIEVERS. This means they make their living finding things, picking them up and bringing them back–they’re supposed to be mouthy! They also tend to be witless and hyper until they’re about 3-5, then they suddenly turn into the greatest dogs ever. The trick is not killing them before they turn cool.
I have a Malemute, but I would definitely not recommend them to a novice dog owner–they’re too smart and independent for most people. Training a Malemute is an exercise in “what’s in it for me?” and Og help you if you can’t convince them to mind! They dig a lot, too, but don’t bark much. Oh, and if you want a watch dog, pass on by–the Malemute will lead them to the good stuff for a sandwich…
There’s a similar issue with border collies in that they’re usually smarter than the people who own them and if they don’t respect you and if you don’t keep them busy they will be holy terrors. Great agility dogs, though…
Golden retrievers are very popular, and with good reason. They’re beautiful, smart, gentle and very good with kids. They do need grooming, though, to look their best.
Australian shepherds are pretty awesome dogs, they have a lot of the smarts and herding instincts of the border collie but they’re more gregarious and playful and tend to love kids. They aren’t too huge and intimidating for smaller children to play with, running around the 40-70 lb range. Queensland blue heelers are similar type dogs, less maintenance due to a short coat.
St. Bernards drool. A lot. All the time. In bucketloads. If you can’t handle this feature, don’t go for one. Also, very large breed dogs are surprisingly delicate while they’re growing, need VERY high quality food to stave off bone and joint problems later on and have pretty short life spans. On the plus side, a large breed dog actually requires less room and exercise than some small breed dogs, such as Jack Russell terriers and the like.
In general I’d recommend dogs from the herding group most highly for an all 'round family dog. They’re bred for smarts, trainability, paying attention to people, and low aggression. A herding dog that gets pissed and bites the sheep is not a good herding dog, so they’ve been bred for patience and good temper over many generations.
I’m a big-dog type person, I’ve owned Malemutes, huskies, German Shepherds, Aussie shepherds, Dobermanns, Rottweilers, Border collies, Labs and English Mastiffs. The only small dog I’ve ever owned was a Chihuahua I was given as a teenager. Can’t say I’d recommend one of those to anyone!
Please, please, PLEASE do try to adopt from a shelter or rescue group rather than buying a puppy from a breeder! Rescue dogs need you and will repay your extra effort a million times over in loyalty and love. Oh, and spay or neuter any animal you do end up with, because it’s a tragedy how many dogs end up euthanized for lack of good homes.
