not 100% sure , but I think that Afghans are susceptible to twisted gut (torsion) , as are Weimaraners , which I have one of . Other dogs susceptible are Greyhounds , Dobermans etc . It can be brought on by vigorous exercise after a large meal , so better to feed two smaller meals per day , than one large , and don't allow the dog to run about immediately after eating . The content of the meal matters little , ie complete dry or raw meat or even cooked . It is just large quantities and then strong exercise that can cause it .
However , a dog allowed to eat raw meat in large chunks would cause problems possibly , as would allowing a dog to eat a large amount of complete dried food !!. I doubt that the torsion was caused by eating meat ,( raw or otherwise ) , as after all , dogs are meat eaters .
I haven't seen that many wildlife programs with wolves opening a bag of complete , well balanced dried dog food !!!
Up until about the mid 1970's we used to feed our dogs on food brought round in a van , there was tripe , bones and all sorts of other cuts and bits of meat . Before the van it came round on a wagon pulled by a horse . I can remember that until I was about 10 or so , then he got a van as his horse got too old . It is only a relatively modern thing that we can go and buy bags of dried dog food , that we are told are complete and well balanced and needed by all dogs . We are told this by the companies that make the stuff ? mmm
My dogs are no healthier now than our dogs were all those years ago . Our dogs were always healthy and well fed on a variety of food , as were most other people's dogs .
I also worked in a rendering factory that supplied all the major dog food companies . You would not buy ANY dog food from a shop if you knew what went into dog food either tinned or dried and bagged.
Just as what we ourselves eat differs , then so does what we feed our dogs . Whether you chose to feed tinned with biscuit , or complete dried , or meat either cooked or raw with veg , matters little really , as long as you feed enough and as varied as possible, you can't do much more for your dog .
