You have ABSOLUTELY come to the right place, my friend!
Some couples choose to have a member of the bridal party or someone special (like a family member or friend who isn’t part of the bridal party) walk their dog down the aisle, or alternatively, we can also take care of that on the day (particularly if your dog tends to pull a fair bit, as this saves someone from your bridal party potentially being pulled over if they’re wearing heels and a tight dress!).
The bridal procession order is totally up to you too; some couples choose to have their dog come out first, and some right before the Bride walks down the aisle. Some couples opt to have their dog as their flower girl/boy or ringbearer, or not at all.
We’ve also had a few couples choose to do the entire bridal procession, then the Celebrant says something like ‘Now we couldn’t make today happen without an extra special guest...’ before the dog walks down the aisle as a surprise, or you can also keep them as a secret ringbearer who appears when the rings are required.
There’s so many options, so it totally depends on what you imagine for the big day!
