oh and BTW, that 25% less calorie thing from the purina lifespan study works for humans, too.

As soon as I stir in bed in the morning, Sweety starts whining telling me it's time to eat. Then Zeus jumps off the bed and they both head out into the kitchen. It's the same every day. On fasting days, once they realized that it's “Food-less Friday” (#FF), they both usually just got back to sleep (after a bathroom break). After that it's business as usual.

I would say that they seem more alert on fasting days, probably because they're waiting for that one morsel of food to fall on the floor. =/

I wouldn't think that vomiting bile would be the result of fasting for one day.

I found the following here. It doesn't sound like the vet community has a really good handle on why dogs vomit bile.

“I have researched this question in the past without finding a really good answer for what causes vomiting in the morning (mostly) in some dogs or for what to do about it.

The prevailing opinion is that many of the dogs that exhibit this clinical sign have inflammatory bowel disease (IBD) or some other condition that causes a decrease in gastric mobility. This may lead to gastric reflux when the dog first gets up or when there is excitement, as your vets have suggested. The gastric reflux causes some dogs to vomit. It is highly likely that there are a number of causes of this behavior but this theory does account for a big portion of the affected dogs, I suspect.”

Sweety & Zeus were not happy about not eating for the day, of course they've been conditioned TO eat every day, and beyond that, most dogs I've ever knows would eat 24/7 if they could.

It was worse for Zeus than Sweety. He sat there and burned holes in my head with his eyes for a bit, LOL, but after that they were good.

The only way I could see a dog becoming hypo is if they suffered from diabetes. Adult dogs, with the exception of lactating bitches do not require the intake of carbohydrate, their liver's are able to synthesize glucose from fats and proteins which is how they derive energy from their food.

Many people seem to be of the misconception that a dog's digestive system works in the same way a human's does, but this is flawed thinking.

The preferred source of energy in humans is from carbohydrate. Our liver's convert carbohydrate into glucose and ultimately into ATP, the only usable form of energy in the body. As mentioned above, dogs synthesize energy from fats and protein. So, I think one of the biggest things we need to do, is to recognize the differences between canine and human biology and physiology. If we can do that, we'll have healthier dogs who will be with us longer.

There is a good explanation of a dog's carbohydrate (or lack thereof), requirements here.
