Probably because you feed it or some one in your house did and Its hoping for some love or food
Sit, stay, lie down, shake, come here
I feed a nice white germen Shepard stray dog in my neighborhood, and I feed him the following food every day: 1 can of canned dog food (Alpos) on top of 1 full bowl of cheap dry dog food. (Purina) Keep in mind that many strays are extremely hungry, and that they will gladly eat anything. The canned dog food will fulfill a portion of their daily nutritional value, and the dry dog food will fill their stomach, so that they won't have hunger pains.
Sit
You can! Dogs read your body language unbelievably well. Also, when you say "Come", a dog knows that that means to come to you, if you've trained your dog. It's the same with "Sit", "Stay", "No", "Off", "Down", and others

A dog does. It can do all the tricks. I have a puppy and he knows sit stay come all thos cool tricks. Again I say a dog.
Stray cats may seek shelter, food, or attention when they sit outside your door. They could be lost, looking for a home, or simply exploring their surroundings.
by telling him to sit
"Would you like to sit on the chair with me, dog?" is a question asking if the person wants to share the chair with a dog.
his dog
You dont need a book our dog can sit give its paw and lie, use treats put the treat behind your back and keep on doing that... maybe pat it bottom down and when it has learned sit keep on using the dog treats and make sure you give the treats in the end or your dog will never! do it evertimeAnswer: I would love to tell you how to train each thing but I would end up typing a novel. You can google search "how to teach a dog to sit" a lot of those sites have the right way of teaching a dog obedience cues which is using 'luring' technique. Just remember to always set your dog up to succeed, don't get him to sit once then expect him to sit when you say "sit". Always teach the Behavior first, then add the verbal command. So get him to sit then give him a treat immediately when his butt touches the floor. Once he understands that this position will get him a reward he'll offer it more often. At that point you'd add the verbal cue "Sit". If you continuously say 'Sit' to a dog the word loses all meaning. Only say it once when you begin using the verbal cue.
just say in the mic sit
