I found it interesting when you mentioned giving the dog a job and making sure that the person is patient with it because they will not totally obey in the beginning as the act is very difficult for them. If that is the case, I need to talk to my brother about working on his patience as he plans to train his pit bull, Peachie, to fetch the newspaper for him. Since he is not exactly very patient, it might be for the best that he hire a professional to be patient on Peachie for him.
^{Most dog training programs use OUTDATED force and dominance techniques. This is proven NOT to work by the latest research. My methods are force-free and gentle. They rely on the latest science in dog behavior research to create a strong bond between you and your dog and create positive emotions in your dog as opposed to fearful ones. They only reinforce the behaviors you want.}
While it is best to start training your pup at an early age, you can train also train an adult dog to protect your children. It's just a little harder and may take more time. Bear in mind, you instill a sense of loyalty by the way you treat your pup. The more loyalty he feels towards you and your family, the more naturally protective he will be and the easier it will be for you to train him. 
At first you are going to let the puppy see the food in your hand so that you will have her attention and can use it to guide her into position. As your puppy begins to comply more readily, you can start to hide the food in your hand, but give the command and repeat the motion or signal that she has learned to follow. Soon the puppy will come to expect the treat each time she performs the task. Then, signal and give the command, but when she performs the task, reward only with praise and give the puppy an affectionate pat. Next, you can begin to vary the frequency, giving praise with “good dog” and perhaps patting each time, but giving the food randomly, perhaps every 3 or 4 times. In time, the puppy should respond to either the hand signal or the command.

Once you have determined to bring a new dog home, the real work begins! Especially if they have not been house broken the dog must be taught obedience. This can be a very frustrating and even thankless task. Initially, it seems like a lot of work for very little effort. The dog does not appreciate the training; it seems like you are constantly in a battle of wills and oftentimes your family will blame you for every failure or backwards step that the new animal takes!

Feed your dog a high-quality diet with appropriate amounts of protein. If your dog spends most of his days lounging in your condo, don’t feed him food with a protein level that is ideal for dogs who herd sheep all day. The money that you will spend on feeding an appropriate quality food will often be money that you save in vet bills later on. I recommend you always check with your veterinarian for the right diet for your dog.

If you leave your dog home alone, and return to find that Fido has redecorated, your dog is likely anxious about your being away. "This is separation anxiety — the excessive chewing to relieve the stress it feels; continual barking; pacing; whining," Victoria Stilwell, author and dog trainer, told Sandy Eckstein for WebMD. "Sometimes, if it’s really excessive, a dog will chew through walls. I’ve had dogs jump through windows, through glass, to get outside. Most of the destruction is centered on points of exit."

In order to be certified as a therapy dog or emotional support dog, animals need to receive an evaluation/written designation from a licensed health professional: social worker, physician, psychiatrist typically. As for service dogs, which are allowed to accompany their owners into most businesses and pet-restricted areas, they can receive training, certifications, and registrations from several organizations such as TDI and United States Service Dog Registry. These certifications are not required by the Americans with Disabilities Act, but may streamline the process of getting a dog access to typically off-limits areas. Service dogs and therapy dogs are not the same thing. The same dog might fall into both categories, but therapy and emotional support animals are not recognized under the ADA.

One thing that is very important with desensitization exercises is that during the retraining process, it is important not to expose our dog to large doses of the fear stimulus. The key with desensitization is to start small, and only very slowly increase the strength of the stimulus. In this way, our dog is able to stay calm, learn from the experience, and can slowly rebuild confidence.

Practice getting your pup excited (which is always easy to do). Have a leash on your pup. Jump around, move your arms, talk in a high voice, then say “settle down” and use the leash to lure into a down position. He doesn’t have to stay for more than 2 seconds. This is a good way to learn how to control your pup when he gets rambunctious without you initiating it.

^{Work on only one part of a skill at a time Many of the skills we want our dogs to learn are complex. For instance, if you want to train a solid sit-stay, you’ll need to work on teaching your dog that she should stay in a sitting position until you release her (duration), she should stay while you move away from her (distance), and she should stay while distracting things are going on around her (distraction). You’ll probably both get frustrated if you try to teach her all of these things at the same time. Instead, start with just one part of the skill and, when your dog has mastered that, add another part. For example, you can work on duration first. When your dog can sit-stay for a few minutes in a quiet place with no distractions while you stand right next to her, start training her to stay while you move away from her. While you focus on that new part of the skill, go back to asking your dog to stay for just a few seconds again. When your dog can stay while you move around the room, slowly build up the duration of the stay again. Then you can add the next part-training in a more distracting environment. Again, when you make the skill harder by adding distraction, make the other parts-duration and distance-easier for a little while. If you work on all the parts of a complex skill separately before putting them together, you’ll set your dog up to succeed.}
Scents can also help calm a dog's anxiety, and DAP is a popular option. It is a synthetic chemical that is based on a hormone produced by lactating female dogs that help keep her puppies calm and increase their bond with her. While scientific studies have shown that DAP does work with puppies, it isn't as clear if it works with anxious adult dogs. Even so, there is the possibility that it can help, and it can be one of several tools used to help an anxious dog. It comes as a plug-in diffuser with vials that last about 30 days, and humans aren't able to smell it.
If possible, try to avoid letting your dog be exposed to dark rooms. Anxious dogs will try and escape and generally look for dark rooms such as a closet. This isn’t an ideal place for them, so try and keep these rooms closed so they are in a well-lit room. Attempt to spot the signs of an oncoming anxiety attack so you may prevent it from happening. If your dog knows how to sit and stay, nuances like these can help reinforce positive reactions to their perceived “negative” environments.
Stage three: Hold one treat in your palm in front of the dog and one behind you in the other hand. Instruct your dog to “leave it.” If the dog gets too close to the treat, make a fist to hide the treat and say “no” or “uh-oh” to show the dog that he won’t be rewarded or noncompliance. When he obeys the “leave it” command, give him the treat that’s behind your back.
Humans aren't the only species that can be calmed by soothing music. Many owners leave a television or radio on when they leave the house to help a dog feel comforted. But there is also specialized music that one can play to help particularly anxious dogs. Through a Dog's Ear is a selection of music specifically aimed at calming nervous dogs. The website states, "The over-arching psychoacoustic theory informing Through a Dog’s Ear is summed up in just two words — simple sound. This term refers to the process of minimizing intricate auditory information found in most music. The music of Dog’s Ear is intentionally selected, arranged and recorded to provide easeful auditory assimilation." The music can help for a range of situations like separation anxiety and travel anxiety. There are even compilations designed to help desensitize a dog with noise phobias.

Things you can do at home to relieve your dog's anxiety include making a special space just for Fido where he can feel safe when you leave, and playing music. I always leave music on for my dog when I'm away, and the Washington Post reported that shelter dogs who listened to Canine Lullabies, by music legend Terry Woodford, adjusted better than other dogs.

Finally, a visit to the veterinary office may make your dog feel leery and cause anxiety. Think about the conditions of the situation and why your pet may feel extra jumpy. Take him for a walk beforehand to get his energy out. Soothe him as you put on his leash or put him in a carrier. The more you remain by your dog’s side and let him know you’re there for the duration of the visit, the more comfortable he’ll feel.

Readers, you can use treats to train and it doesn’t cheapen your relationship. Your dog loves you unconditionally, remember? It isn’t “bribery” any more than using toys, attention, etc. is bribery. I can’t tell you how many times I stepped on my puppy’s toes while he was learning to walk on a leash, and he still loves me. And even if it were, your dog (and you too) deserves the best quality of life you can give him, which means clear expectations and an enriching life, which requires good citizenship. If you have one of those dogs that isn’t food-motivated, you can still use positive reinforcement.
Head halters are an alternative to collars that works similarly to a horse halter. The halter fits over the dog's snout and behind its head (leading it to sometimes be mistaken for a muzzle). Halters reduce the dog's ability to successfully pull on the leash, but do not eliminate it. If the halter is used with a sharp jerk on the leash, neck injury to the dog may result, but used correctly head halters have not been shown to cause harm.
In the car, these solutions may also help with mild motion sickness your dog might suffer from. On road trips, take plenty of breaks so your pet can have room to roam and urinate. This should all be factored into your travel time so there’s plenty of time for stopping along the way. Being cooped up for too long is one way to surely make your dog feel restless and anxious.
