How can i train my puppy to behave well in public?

Get him into obedience training. You will get a ton of advice and your dog will get socialization.

get him used 2 ppl and u should train him in dog skool.

You need to get a trainer to help you out. There isn’t an easy solution to the problem other than to get him to start listening to you. A trainer will help you to be on your way. Good luck!

keep taking him to places that have animals. Make sure you have him on a leash. If he starts to bark have a soda can that has coins inside of it with you and shake it at him. This worked for my huskey.

My puppy, a golden, 7 months, jumps on people a lot. Your puppy is probably stressed out and is unsure of his environment. You need to take time and make sure he knows that you are the boss. If you let him continue his aggression it’ll only get worse as he gets older and bigger. Every time he makes an aggressive move (growling, barking, etc) give him a sharp tug on his collar to the side (get a choke collar, may not seem nice, but if you do it right, it should work) and say loudly, but firmly, NO. If you keep repeating this he should start to understand that his behavior is unacceptable. Also, before you leave the house, make him sit and make sure he is calm. Do not let him leave the house ahead of you, because if you are in front it means that you are the leader. I would also invest in a good puppy obedience class. Good luck and hope that helps. Oh, and make sure he gets socialized with other dogs and people. Very important.

Socialzation is the key. Have one of your friends come over until the dog is comforturable, the next day have two, work your way up till you have about five friends. That way your puppy will get used to a lot of people. He is new to your neighborhood and still pretty young, it’s normal for some dogs to behave like that.

What he is probably displaying is fear aggression because he’s not socialized and feels insecure.
Since you adopted him he’s been shown things he’s probably never been around.
Don’t nuture this type of behavior (petting, sweet baby talking) while he is in this state of mind. You’d only be encouraging it.
I seriously recommend enrolling in an Obedience Class (I’ve enrolled my pitty and me in them twice because they were so much FUN!). Obedience class provides training, it improves the relationship you have with your dog, and you get to meet other dogs and people, and your dog is able to be socialized in a safe and secure manner.
The last thing I’ll recommend and most likely the most important, is Exercise. You need to become the pack leader and take him on a journey through the territory. Dogs are migratory animals, if they were wild they’d be walking/running to explore their territory, etc. We need to fulfill that need. It doesn’t matter what breed it is, all dogs need it.
So, when you’re walking make sure you’re infront of the dog or the dog is walking calmly by your side.
I raised my pitty "Cesar’s Way" from day one and I’ve never been so close to a dog in my whole life, I’ve fostered, adopted, cared for etc A LOT of dogs in my life but this is the most awesome relationship with a dog I’ve ever had.He’s got a couple books out now, I think you should read. http://www.cesarmillaninc.com

Anyways. Here’s the summary of needs you need to fulfill to help your dog in all areas of his life:
Exercise (walk by your side, structured sports), discipline (rules & corrections), affection (when the dog is calm and submissive and on your terms) and stimulation (training, playing, toys).

I hope this helped, I wish you luck and thank you for opting to adopt!
