Activity for Kellie

My FH has requested our two dogs be a part of our wedding. I'm on the fence about it (& have lots of time to think it over lol) but would like to hear some experiences others have had with dogs being a part of a wedding

I'm thinking of doing something like this (see below for inspiration pic) and was wondering if anyone had any opinions on whether to go to a florist and get real greenery or if something from Michaels will do just as well TIA
