In home it is cute roaming around but when it goes in crowd it is scared of people and start barking and hide behind you but
With patience, training, practice and kindness you will help your pet relax, understand you and do what you ask.
Many dogs bark out of fear. your dog barks may be due to boredom, excitement, guarding, etc
The training methods require no more than treats and practice. However, if you find it difficult for your dog to relax or learn, then you may need to visit your vet for meds for aggressive dogs. These will only be needed in some cases and your vet should work along with your training plan to reduce medication as the dog progresses.
Understanding fear and stress in your dog
Almost all dogs are afraid of something and most of the time this is not a problem because it does not show very often.
Methods to decrease your pet's stress levels
1- Keep your dog away from the fear-eliciting stimulus for at least a week (to help those stress hormones dissipate). If necessary keep him home and take him out only to quiet places or at quiet times. Do this until you see some progress This is very important to solve your barking dog problem.
2- Use canine massage: This might seem a little silly, but it is becoming very popular and you can learn how to do it yourself. The idea is to switch from "petting" to "massage" and incorporate it into your daily routine. It will increase flexibility and circulation as well as reduce stress, just like it does in humans! The best part is that you will bond with your furry friend even more
3- Play with your dog: Playing tug-of-war, fetch, chase and other games strengthens the bond between you and your canine friend and makes him feel relaxed and full of the good stress hormones. Training exercises can also be used to enrich your dog's life.
4- Try dog relaxing products: these are natural remedies for aggressive dogs to help them calm down, they can help solve a fear barking dog problem. They are design based on physiology, anatomy and the study of canine behavior. The ones I recommend here are useful and have helped lots of dogs. Note that all of these products will help but will not solve the problem on their own.
I hope it will help your problem
