Yes, some breeds are more prone. Any deep-chested dog is more prone than types. Also I suspect that some genetic lines within a breed can be pre-disposed to it based on observation.
I tend to feed free choice. Everyone is fed in two meals (right now at 5pm and again at 7-8pm). I put out the dry kibble and then give everyone 1/3 can of wet food. The dogs normally eat the wet and then may or not eat the kibble. That kibble stays out. They can free feed until it's gone. Sometimes the dog is extremely hungry and will go clean up the kibble left in another's pan. If the kibble is still in the pan at the next feeding then the amount of new kibble is reduced to match a regular feeding. I've not (knock on wood) had an issue with bloat. The dog gets to graze as the mood strikes them. Being SAR dogs, I don't have the luxury of knowing when the pager will go off. I've put food down and then immediately left for a search. I've fed them during a search. I've come home after exercising them and put down food within 15 minutes of coming back. After a feeding, I've had them go into the backyard for a game of chase and body slamming. I also do not have any dog with food aggression issues. From what I've been told this type of feeding makes them overly prone for the risk of bloat but so far, no issues.
However, I DO NOT have dogs that will overeat. Unlike labs or some other high food drive dogs, I can throw 100lbs of dog food into the middle of the floor and they only eat a cup or so at a time. Some folks put down the bowl for 20 mins and then pick it up after that time if still unfinished. I don't do that as I feel it encourages the dog overeating when at that time its not hungry or conditions them to bolt the food down because its now or never, until the next feeding. I feel that by allowing them to graze through the day it actually reduces the risk of bloat. I don't wet the kibble down as this makes it heavy and sits on the stomach harder (IMO) because of the water weight.
In the end, it's doing what you feel is best for your dog. I don't exactly recommend my way because these are my dogs and the years have taught me what works with mine. I sure as hell could not feed this way if I had labs instead of shorthairs. Your dog and your situation will be different. Do what you feel is right and works in your situation.
