Help him relax when he comes home. When your puppy gets home, give him a warm hot water bottle and put a ticking clock near his sleeping area. This imitates the heat and heartbeat of his litter mates and will soothe him in his new environment. This may be even more important for a new dog from a busy, loud shelter who's had a rough time early on. Whatever you can do to help him get comfortable in his new home will be good for both of you.

There are many factors that go into choosing the right training school for you and your dog. Certainly distance is a consideration; however, convenience shouldn’t be the only factor that influences your decision. Other things like training methods, appropriate classes for your needs, compatibility of the instructor’s personality with yours, and certifications of the instructor should also play a role.

Thank you for this very informative article. I've been trying to find more information about what may be causing the symptoms my dog has and many of these fit her. So many other articles categorise these symptoms as reactions to specific situations (noises, separation from owner), but she seems to exhibit these symptoms pretty much every day, independent of any discernible environmental stimulus. This will help me talk to the veterinarian about it during our appointment.
First, teach the release word. Choose which word you will use, such as “OK” or “free.” Stand with your puppy in a sit or a stand, toss a treat on the floor, and say your word as he steps forward to get the treat. Repeat this a couple of times until you can say the word first and then toss the treat AFTER he begins to move. This teaches the dog that the release cue means to move your feet.
While you may be more concerned about one or two issues, it's important to work on all behavior and socialization training when introducing obedience training at home. Having an idea about what you want to focus on in the beginning will help you get off to the right start. Just remember to touch on all behavior concerns throughout the time you spend training.
_{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.} 
This is a tough one because she obviously has a learned, deep-seated fear of crates. Forcing her into one will only make the problem worse. You can try desensitizing her by feeding her in the open crate, playing with toys in it, and seeding it with treats, but this all takes time. If she is truly distressed, then a gentle sedative from the vet is going to be the most humane option.
I have two toy poodles who are brother and sister(both neutered), and the boy poodle(Keanu) is very very super attached to me. I just thought he was really affectionate, but it’s gotten to a point where all he does is follow me around, stare at me all day with sad yearning eyes, whine in a tiny tiny voice endlessly untill I hug him, and when I do hold him he is really nervous and agitated and doesn’t really enjoy the hug but just frets around, or licks me so intensely, which goes on forever untill I have to stop him. My husband loves both dogs but since Keanu is absolutely just obssessed with me my hubby thinks Keanu wants me all for himself and is even jealous of my hubby. Another thing that kind of creeps me out now that I think about it is when I open my eyes in the morning, his face is right in front of me, like he has been watching me all morning…This weird behaviour was not evident when they were puppies, and I think it was so gradual that at first I didn’t realize it was odd.
Do not let your dog "lean" on you either when you are standing up or sitting down. This is not a sign that they like you. This is a sign of dominance. The dog is encroaching into your space. You are the leader. Stand up and let your knee or foot nudge them out of your space. Praise the dog for getting up. Give the dog a command to lay down on their bed or go to their crate if you need to manage your personal space more effectively.

Are you thinking of adding a new dog to your life? Would you like your current dog to be better behaved? Would you like to train your dog to serve your needs instead being trained to serve its needs? Attending dog classes led by a professional trainer is the best approach, but not everyone can afford classes. These tips are a good start to training your canine companion. There are many philosophies and approaches to dog training, so do your research and learn what works for you and your dog.[1] Regardless on which approach to training your dog you take, building a good relationship with your dog is essential to being able to train effectively.

Note though that the dog training profession is not well regulated, so when I was looking for a trainer for Sephy, it was not always easy to find a good one who could give us accurate information about dog behavior, and is good with dogs. I found that it was very useful to read up on dog behavior on my own, so that I could better understand Sephy, as well as quickly filter out all the nonsense “trainers” we encountered.

^{To train your dog to come when called, start on leash in a quiet area. Back away from your dog while enthusiastically telling her to “come!” Only give the command once, but be enthusiastic, and keep your body language relaxed and open. You can show your dog a treat to encourage her to head your way. Once she starts towards you, say “yes!” (or click) and reward her with a treat.}
