Careful + of/about/with/on

[Tung Quoc]

Dear teachers,

In my class, my teacher wrote on the blackboard:

Be careful ......the dog.
a. of
b. about
c. with
d. on

My teacher chose of.
But in my English - Vietnamese dictionary, I saw: careful + of/about/with/on.

Do you think the 4 a,b,c,d above are all correct and interchangeable? If not, the difference is what?

Best regards
Tung Quoc

PS:
1/To emphasize "Be careful of the dog", can I say:
Do be careful of the dog?

2/ To emphasize "Don't be careful of the dog", can I say:
Don't you be careful of the dog?
