I want to have a full grown pomsky

Hello, I love dogs and I found an adult pomsky ad. He said he would give it to me because the owner will have a baby. But I do not know anything about pomsky care, and I have a five-year-old son. Adult pomsky who has never lived in a home with children. Should I take it? I read an article about pomsky on a site, but the comments of pomsky owners are very important to me.
