Welcome to Dog Forums!
Well, I'm not sure how others will feel... But I don't think it's that big of an issue as long as your dog is getting the required amount for his breed/body type/weight, so on...
I feed my dog once a day, somewhere in the afternoon time, he most usually poos in the morning or late at night; Since sometimes I'm not home during the afternoon time, I rarely, if ever, worry about coming home to an accident.
Donatello has eaten only once a day for almost a year now and he's doing fabulous; Both vets I've gone to both praise him on his weight... I've come to find that feeding once a day, twice a day, or breaking up it up into smaller meals is one of those "personal preferences".
As long as the dog is healthy, and like I mentioned, getting the required amount of food, I don't think it matters when or how often he eats.
Oh, and I do want to add; I suggest cutting back gradually. Instead of just cutting out a meal, would I offer him less in the morning, and more at night over the course of a few days or weeks, as long as you and the dog feel comfortable; Then I would substitute a healthy chew or a bone in replace of his meal for a few days until he's adjusted... That's how I adjusted Donatello around this time last year, and I received this idea as a suggestion from someone else on here, too.
I'm sorry about the SA, I'm sure that's really tough, but there are plenty of people here with experience in that department that might be able to help you if you'd like.
