The answer to this question is something that may surprise you – but it is actually quite far.A dog’s sense of smell is much more sensitive than ours, and they are capable of detecting even faint odors from a great distance away. This can help them to track down food sources or dangerous prey, and also help them to find their way home.Because of this, dogs can smell food that is out of sight, even if it is in the fridge. This might mean that you leave leftovers out for them to snack on, but if they like their food cold, you may have to make sure that it isn’t in the fridge too long!Dogs also have a great sense of smell when it comes to blood, and can detect a wounded animal from great distances away. This can enable them to help humans out in situations where they need extra help, or even alert them to potential dangers while they are alone.
How Far Can dogs smell into the ground?
Most dogs have a keen sense of smell so it is probable that they could smell into the ground if they wanted to. However, the ability to ‘see’ into the ground is another matter altogether.Dogs can ‘see’ into the ground by perceiving reflected light which can be seen in their eyes when they are hunting prey or detecting movement underground. This ability enables them to track their prey by following its scent trail.However, while dogs may be able to smell into the ground, they are unlikely to see anything or find anything as a result. The light reflected into their eyes when hunting in the ground is too dim for them to see by daylight. Night hunting may be possible though.
