When referring to a person or animal you must use who, whom, he, she, etc. We do not refer to them as an it or that.

I disagree with Lee. Only people are referred to as who. Animals are referred to as that or which.

============================
Thank you for your help.

1. I have a dog, Lucky. He is cute.
2. I have a dog, Lucky. She is cute.
3. I have a dog, Lucky. It is cute.
[Can we use all the expressions? Which one is commonly used?]
=> Do you mean we can use all the expressions in the three sentences?

4. I have a dog who is very smart.
5. I have a dog which is very smart.
6. I have a dog that is very smart.
[Which relative pronoun do we have to use?]
=> Do you mean we have to use #5 and #6? Is #4 ungrammatical?

Yes, you can use all three expressions in the sentences 1, 2, and 3. However, the common convention is to use "he" when referring to a male dog, "she" when referring to a female dog, and "it" when referring to a dog of unspecified gender. So, the commonly used expression would be "I have a dog, Lucky. He is cute." if Lucky is male, "I have a dog, Lucky. She is cute." if Lucky is female, and "I have a dog, Lucky. It is cute." if the gender of Lucky is unknown or unimportant.

Regarding sentences 4, 5, and 6, all three options are grammatically correct and commonly used. The relative pronouns "who," "which," and "that" can all be used to refer to a person or thing respectively. So, you can use any of these options based on your preference. Therefore, "I have a dog who is very smart," "I have a dog which is very smart," and "I have a dog that is very smart" are all grammatically correct.
