My husband is very fond of dogs. Is it safe to keep a pet dog around my 2-year kid ?

personally i have dog at home with my 2 boys.. since baby till toddler they have been in good terms with her... of course u do have to watchout for the hygiene, ensure washing of hands after touching the doggie.. another point is that i will always ask my kids to only touch it with me around as never know they will provoke it in any rough handling ..
