I have a 1yr old male yellow lab and he has some habits I can not break.
1) he eats poop, I have tried cleaning it up but he gets to it before I do, I have changed his food and tried forbid.
2) he jumps on everyone.its like he is a kangaroo
3) he barks for attention and then when you give it to him its never enough, he does not know when to stop.

Please help.

1 You could try adding pineapple juice or canned pumpkin to his food.

2 Consistently is very important in correcting jumping and other problems. Quickly correcting him every time he jumps on somebody is very important. Something bad has to happen each time. People are successful with a number of different things. One of the most gentle is to grab his front paws and hold him up. The traditional knee to the chest or step on his paws work well too. Turn your back and step away. In each case apply ''Bad dog, its name off!'' in a firm, but not loud voice. Go ahead with it even if he is too quick to add a physical correction. Everybody will have to do one of them every time he jumps up.

3 Try petting him a little and then patting him on the top of the head and saying ''Enough''.

The jumping stuff will work eventually if everybody is consistent. The other 2 are things I have read in a trustworthy source.

Although I agree with labman, I personally, am not a big proponent of the knee in chest, if that is actually what he is suggesting. Not sure because of the wording. If you can bring your knee up and in front of your body, just to block his contact with you, that works as an obstruction to his getting what he wants without hurting him.

Although I have worked with labs, I do not have the vast experience with them as labman has. Like pitbulls, they can be a handful when young. And, your dog, although full grown is still young and immature at one year of age. The grabbing of the front paws and holding them up is a great, non-threatening way to get him to stop. Hold the paws up longer than usual. They get very uncomfortable and try to get back down on all fours. When that happens, keep holding the paws up. Basically you want to take him past his comfort zone. Do it every time he jumps on you. He will eventually make the connection that if he does this, discomfort will be associated with this.

Labman is absolutely on target as usual. Consistency is the key. I found that when I walked in the door after being out, the best thing was to "walk through" the dog. Act like he is not there. If he accidentally gets his paws stepped on while you are trying to bring in groceries, he will learn that he needs to get out of the way and wait for you to acknowledge him. Ignore him every time he does this until he sits or lies down. Once that happens, pat him on the head and say "Good Boy" and then walk away. This is all part of placing yourself in the alpha position. If you haven't already done so, please read labman "sticky" at the top of this forum. There is some very wonderful and valuable information in there.

Regarding the barking for attention, it is another thing that you will have to kind of turn a deaf ear to. Walk away. Every time he follows you, move out of the room. Act like you don't hear him. If you can handle ignoring him completely, he will eventually stop and sit or lie down. As soon as he does that, very calmly walk over to him, give him a pat on the head and say "Good Boy" and walk away. If he starts barking again after that, keep up the same routine. He will eventually make the connection. As labman says, consistency is the key. This won't happen overnight. But, eventually, you will be rewarded for your patience.
