for my two pennies worth, I think that bloat is more related to the speed of consumption and weight of food and its constituents rather than the height you feed it from. ( "wild dogs have to work for their food and can not consume any quantity of `concentrate' very quickly, they also would have a more toned musculature around the stomach due to their pack behaviours of carrying food back to the non hunting family members. Their drinking behaviour and timing is also different ) Dogs are not herbivores and should not be compared in this respect, herbivores are grazers and are therefore built to consume food from the floor, however, again not concentrates and smaller regular quantities rather than in a concentrated period, thus bloat in herbivores occurs mostly due to impaction followed by gaseous fermentation and expansion, rather than torsion. An interesting aside is the various methods ( and contraptions) we use to slow down `gulpy feeders'. I found the cheapest and easiest method is to find a food the the dog does not particularily like, ( mine are not to keen on chicken and liver mix) and mix a little of that in with the food that they gulp, in trying to pick out the best bits the dogs consumption is slowed dramatically Of course this doesn't help if you have a `dustbin' of a dog Peter BenB This has proved more interesting than I thought it might and I am pleased that it has not
