My advise to you is to always remember that this is YOUR wedding and YOU are the one that calls the shots. I'm sure some people will object to you having the dogs in the wedding but if it's important to you then they should be there. I personally think it's a great idea. I also would suggest that well before the wedding you pick someone to watch over and be responsible for each of pups. You and HJ will be very busy and won't be able to constantly watch the dogs.

I'm going to stress that this is your wedding be sure you get everything you want, don't let others push you around. If I could do my wedding all over today it would be completely different from what it was. My mom planned my wedding, I had very little say in it. She completely took over, she invited people I didn't want to invite, she chose the DJ, the place to have the reception, the food, basically everything.
I hate to be the center of attention (a hard thing to avoid on your wedding day). Justin nor I like to dance and neither of us wanted to dance at our wedding, but we were literately pushed and forced to. We were told that if we didn't dance at our wedding we'd regret it later... well guess what, we both now regret that we DID dance.

My sister-in-law (husband's sister) had basically the same experience with her wedding. She was pushed around by her future mother-in-law and ended up hating her wedding. They were having the wedding at her mother-in-laws house and her M-I-L got really bossy and took over.

My husband's cousin did it right. They didn't let anyone tell them how to do things, they did it their way. They wanted a light and fun wedding and that's what they got. She made her invitations by hand. He wore his sneakers with his tux. My husband's other cousin, a 23 year old man was the flower girl. At their reception they had barbecue. They did it their way and they enjoyed their wedding.

If you want Charlie and Jamie in your wedding don't let anyone stop you!
