A big must is training your dog to lie down and settle. Ensure you have lots of tasty treats at the ready for positive reinforcement and stay calm and consistent. This way, when guests arrive, you can give your pup the sit, lie-down or settle, and stay commands.
Work on the greeting
Open the door slowly for your guest and ask them not to acknowledge your dog. You may want to have your pup on a lead prior to their arrival. If your dog is too excited, then immediately, calmly inform her that hyper dogs don't get to say hello by saying “Too bad!”
Many dogs that show territorial responses are often fearful and anxious and just want the intruder to leave. The longer the person stays within the territory, the more aggressively aroused the dog may become. The goal of the territorial display is to get the "intruder" to leave.
Ask your dog to sit slightly away from the door as the new person enters. You can have your dog on a loose lead if it's easier. Reward your dog for continuing to sit as the new person enters. If your dog gets up, the person should move back, and the exercise should start again without reward.
it is usually because they were either bred to be guard dogs or they were not fully socialized as a puppy. When a dog encounters someone they feel uncomfortable around, they want to increase the distance between them and the person. They can either flee or make the person go away by behaving aggressively.
Many dogs are fearful around people they don't know well. Some people automatically assume these dogs have been abused in the past. Usually, this is NOT the case. Most of the time, if a dog fears strangers, she has simply been under-socialized to them.
A confident, controlled dog will not go on barking, become hyperactive, jump, or be aggressive around strangers, which is usually a reaction to fear.
According to Mikkel Becker, a pet trainer who writes for Vetstreet.com, that's normal K-9 behavior. Your dog just wants to see who is there and say hello. You need to teach them to calm down. You want them to learn that the only way they'll get attention and get petted by your guests is for them to sit down.
Put him in the kennel a few times a day for about 10 minutes at a time, along with a special treat or toy, so he gets used to the space. Then, when a visitor comes over, put him in the kennel with the toy or treat. This allows your visitor to enter your home safely and keeps your dog from acting on his worst instincts.
The best way of treating aggression towards strangers is to prevent it by socializing your dog when they are young, exposing your dog to lots of different situations and people in a safe, controlled environment, and teaching your dog that strangers are not a threat to you or him.
While it is never too late to socialize your dog, the sooner you start, the better. Socializing your dog is very important at any stage in their life. It's especially crucial as they get older.
Basic Commands
Teaching your dog how to execute basic commands is a great way to calm their hyperactivity. Basic commands will teach them general etiquette, manners and will also keep them out of trouble. To put it simply, obedience training is the key to managing your canine companion.
Generally, puppies start to calm down when they reach emotional maturity — around 1 year old. However, some dog breeds take longer to reach adulthood and emotional maturity. In those cases, puppies may not mellow out until they hit 18 months to 3 years old.
The main means of helping your dog overcome social anxiety should be through counterconditioning and desensitization.
Excitement. Reactive dogs are often motivated out of excitement (high-arousal), which can lead to frustration. Many times humans have unintentionally created this behavior because dogs were never taught how to be appropriately social around other dogs in an appropriate manner.
The Dog Calming Code program helps establish the very foundation of dog training: the relationship hierarchy that dogs are programmed to seek. Dogs are pack animals. In the pack is where dogs find balance and purpose. Take it from them and they'll feel out of whack!
How to Respond. If your dog is baring his teeth at you or someone else, take a look at his other body language. If you are uncertain of the cause or it appears that the teeth are bared in an aggressive manner, you should carefully remove yourself and/or your dog from the situation.
