Animal blessings

I have a friend who invited me to their church (ELCA) to have my dog blessed. I have heard of other churches doing this, but is there any biblical reason for this type of blessing? I turned the invitation down because I'm not in fellowship with my friend's church and it seems strange to be blessing animals. What is the WELS view on blessing animals?

We do not have a practice of blessing animals, nor does the Bible lead us to establish such a practice. We recognize that animals are part of God’s creation (Genesis 1), and pets can provide wonderful companionship. Considering all of God’s creation leads us to praise him: “Lord God, open my eyes to the beauty of your created world. You made all things to nourish my life and to fill me with wonder and joy. Open my mouth to praise and thank you for your gifts.” (Christian Worship: A Lutheran Hymnal, page 134, a prayer “For God’s Creation.”)
