Thank You?

I was wanting to send out a Thank You card that has a picture of me, DH and our new puppy on it.

Do you think this is a good idea? Or should I just use a picture from the wedding??? I just wanted to show everyone our new addition to the family while still including the thank you for the wedding.

I will still do formal wedding thank yous with the wedding pics, but I wanted to send some of the other ones out to some friends and family.
