I wish I could have titled this "solved" but that would be a tad arrogant and few things in life are 100%. Shipping and handling yes but after that there is a slippery slope. Some things in life are learned by reading and watching, others by experience and still others are just stumbled upon. The following is a 20 plus years combo. First, do your homework about getting a dog, especially a puppy and learn about the specific characteristics of a breed. Learning by trial and error well we have all done that. Second find a trainer. Do your research but make sure you like them on a personal level so that you will trust their every word, Because thirdly you need to learn how to think like a dog and most dog owners do not know how to do that, they only think they do but they are thinking like a human. Your trainer they knows how to think like a dog. The most complex problems like you see on National Geographic with Cesar Millan start with the basics. Sit, stay, yes, no. Read that again. Notice those are all simple one syllabal one word commands. That is all they understand in the beginning. That and tone of voice. A firm NO works. A conversational explanation is confusing at best. Next comes the big debate. Veterinarians, in general say "No being around other animals until they have had ALL of their puppy vaccinations." A trainer will tell you "If you follow this advice you will miss the most crucial socialization era" Solution: split the difference. Get the first vaccination between 6-8 weeks of age and start introducing your new buddy to the world. Go for car rides, meet people, meet other puppies that know not to hang out with the rough crowd. Do not go to the dog park, beach or other areas where large numbers of dogs visit and expose your pet to life threatening viruses. The big concern is usually Distemper and Parvo virus. Unfortunate diseases associated with crowded, unsanitary conditions and unvaccinated dogs that wind up in shelters. If you work from home or can take your dog to work every day great, for the rest of us find day care. This is not necessarily forever but until they mature. A dog especialy a puppy or adolescent sitting at home for 8-12 hours aday alone is a recipe for disaster. Remember think like a dog. Imagine sitting in your home EVERY day ALL day. I would chew up the rug or door too! I have seen a variety of professional veterinary behavioralist diagnosis resolved with mental stimulation. This is not several long walks or several hours at the park but a good 8-12 hours at a well maintained facility that reinforces appropriated behavior aka doggy da. They will sleep good that night and be relaxed most of the next day. This regimen 2-3 times per week with walks, exercise etc. and separation anxiety, boredom, aggression and destructive behavior can be dramatically reduced. If you do have a major problem again find a trainer and watch a few episodes of the Dog Whisperer. You may learn a few tricks and be thankful that episode is someone elses problem. Also, keep in mind like the show some behavioral problems take awhile to resolve, so be patient. Few things in life will bring you companionship and unconditonal love like a dog. Given the proper attention, events that can test or fracture that love can be avoided with a little education and effort.
