Dogs, like humans and all other mammals, get rid of carbon dioxide and absorb oxygen in their lungs during respiration.
No, any effect
Perhaps their sense of smell would alert them, but I do not see too many dogs interested in eating mushrooms.
Because a dogs respiratory system is different from a humans. More accurately, dogs don't hyperventilate when they pant. They are breathing at higher frequencies, but they are ventilating dead space in the airways and not increasing gas exchange relative to metabolic rate. The definition of hyperventilation is a decrease in the partial pressure of carbon dioxide in the blood, which doesn't occur in panting dogs. A more correct term for the increase in ventilation that occurs when dogs pant is hyperpnea.
Dogs smell each other to find out 'who' they are dealing with. Each dog has an individual smell. When a dog smells another dog, they find out sex (male/female), constitution (alpha-based or submissive), and health of the other dog. It is also believed that the age of the dog, possible available food resources, and kinship may be part of the results of the sniffing process. I agree very much with the last answer. When dogs smell each other they are trying to find out the dogs gender, ranking, and were they are from and even if they have a mate or not. So theres your answer!
Yes, they excrete carbon dioxide, water, and feces just like humans do.
providing the body with oxygen and expelling carbon dioxide
No, dogs smell with their noses.

A dogs sense of smell is so acute that it can smell a person who was in a place days after.
it is called cycle because when we exhale we gives off carbon dioxide, and it is absorb by plants, then after the process called photosynthesis it gives off oxygen to the atmosphere, then now we inhale it and after we inhale we exhale the carbon dioxide and goes to the atmosphere then absorb by plants, gives off oxygen, goes to the atmosphere, then inhale it and so on and so forth . . . . . . . . . . . . . . . for shorth will go back and go back. not like the one way flow of energy that will remain.... . . . . . . . . . . . . . . . . . . . . . . .
geranium flowers.... dogs loathe this smell!
No, oxygen is an odorless gas. Even dogs can't smell it.
no because usually dogs feet doesn't smell!!!!!
Yes dogs can smell almost everything in their surroundings.
It is nasty, but dogs like the smell of their owners. That is why some dogs chew underwear and shoes. I don't understand why, but they do.
