http://www.vet.purdue.edu/epi/bloat.htmLike everything there is a lot of contradictory advice about, all we can do is arm ourselves with facts, informed opinions and do what we think is best for our dogs; after all that is all any of us can do.
Bloat kits are all very well if it IS only bloat, unfortunately they will not help if it is torsion. The trouble with torsion is that it can present in many ways depending on the dog and the signs can be "atypical"; torsion requires immediate veterinary help.
Feeding species appropriate food is essential to avoid all life from suffering unecessary digestive problems. Commercial foods contain lots of ingredients that can cause gas which is of course the prime trigger of bloat/torsion hence why the raw regime is recommended as it is grain free fermentation is avoided at all stages through the alimentary canal.
The health hazards associated with raw food pale into insignificance with those associated with commercial foods.
None of mine nor any of the many, many people I personally know have ever been ill on raw food, quite the contrary.
But it is a personal choice.
