Wolf: I once thought of that but now I don’t think so. Because it’s not determined by what a dog necessarily would eat, especially if it’s not hungry, but by what a dog could eat without hurting itself.
something that a dog will eat. meaning that a food item that is very spoiled is not roeh laachilas kelev and is therefor not chometz. this only applies to once edible food.
How is there ever a problem if you find chometz in your house on Pesach? Either it was sold to the goy or it was batul. So you shoildn’t even ever come to Ra’ui La’achilas Hakelev. And certainly one would never have a problem where he owns chometz on Pesach (that he would have to burn or something.)
And then you want to know… if something from itself is fit for” canine but there is an outside force being “pogem” it like a detergent is that also unfit for canine.*************************************
bonus question ….who can explain why by all other halachos as long as it is unfit for humans it becomes muttar
(aino ra’uy lager) while chometz needs to be unfit for canines?

That can’t be so, or chocolate would not be considered ra’ui l’achilas kelev, because it can kill a dog if he would eat chocolate (or at the least make him VERY ill).
