How do I get my dog to be more obedient?

My dog is a 1 year old pit/lab mix and my problem is that when he's around other dogs or people he doesn't obey when I tell him to sit or any other commands and even when I take him out to the backyard and I tell him to go inside the house he doesn't do it right away.

What can I do to correct this behavior?

training how much training does he have and sometimes he could be so interested in everything else and is not listening you need to be dominate to him show him that he needs to listen to You and that you are more interesting hope this helps

Use treats to help the process. If he is in the back yard and you want him to come in, put a treat inside the house with the door open, and say 'Inside' or 'back in' or whatever command you want him to listen to. Same thing with sit and lie down and tricks like that. When he is about to sit down, say sit and when he dose, praise him and reward him with a treat. When you go out with your dog carry a few dog treats with you for a reward if he dose something good. Get him a zap collar if that doesn't work. No, not one of those really cruel electric ones, there is one with citronella spray. Get one and put it on him. For a few weeks, when he doesn't listen to you, tell him you are 'going to get the beeper' or whatever you want to call it and press '1' on the remote for it. It will beep as a warning to him. Press '1' again for the warning if you want to give him a second warning. Press '2' and the collar (If it has the citronella in it and it is on) will spray him lightly with the
citronella. If you press '3' it sprays him with a little more then before. I am pretty sure it is called what it sounds like, 'Citronella Collar'. I hope one of these works. Also, if he is barking at other dogs, beep it and tell him 'no barking' or something. Just to let you know, it doesn't hurt him and you can buy refills where ever you buy the collar. It should be at the pet store.

You still have a puppy. At the dog park, you are never going to get that focus. If you have friends over for a playdate in a controlled environment, you can train him using food. You need a high value treat for him. After a few minutes of play, you call him off. Reward him with the food. You may actually have to walk up to him to show him the chicken and call him off. Have him sit for the treat, then let him play again. You want to set him up for success so you don't want to keep him away from the play for too long. Every few minutes, call him off and give him a treat. The next session, you can let him play longer, then have him sit for you gradually a bit longer. Be sure none of the dogs are food aggressive (which is why you don't ever try this at the dog park, which is a breeding ground for aggression). If another dog comes over with him, great. Treat that dog too. Practice makes perfect. You want to set your dog up for success so you need to make the length
of time you pull him away short, then lengthen it slowly.
