Your dog probably won't like you at first
He probably won't know you
Here are some helpful pieces of advice

Step 1: Welcome

If you bought home a new dog like this
Dont be mean
Tell it to come into your house
Never pick up a new dog
It will probably bite you
Grab some dog food and tell it to come
Evidently the dog will come
If he doesn't just wait all day calling its name

Step 2: Rules

All dogs need rules
When to start making them is when he is doing them
Say no firmly
Letting him know you are the boss

Step 3: Every Bodies Different

All dogs are different
Some obey some don't
Some bite some don't
Teach your dog to do good things
Remember some dogs are slow Learners
Take it easy on them
Step by step

Step 4: Your Dog Is Like a Child

Dogs are like children
When they don't get what they want they growl of whine
When they start whining just look away
When they stop award them

Step 5: Choosing Food

Dogs may be greedy sometimes when it comes to treats and food
You can't take a dog to the store
So, buy them food and if they don't like it make them eat it
Or if you have spare time to buy them food, you can do that

Step 6: Toys

If you dog is a working dog, no need to buy it toys
But if it is a toy dog, you have to keep it busy
Some dogs chew shoes
So, instead of buying toys just give it a shoe

Step 7: No Bed

Your dog probably loves your bed
If you let him sleep on it that's fine
But if it's a problem
Give it a bed
Yes, your dog will never use it
Close your door at night so the dog doesn't come in
