Most of the cats and dogs in my neighborhood eat more rice than meat. They get the left overs and those are usually rice and a few vegetable scraps, fish bones if they are lucky.

Most of them forage, mice, rats, snakes, lizards and any bug they can catch.

The dogs, like most of the people are rail thin.

But, I believe that the dogs like the people build up immunities to a lot the harmful bacteria that they encounter, plus their systems become adjusted to their diet.
