My Dog is almost completely deaf. Would he possibly be able to hear a dog whistle?

Question

He can hear the car horn if you are pretty close.

Answer 1

Only way to find out is to try it. if he hears the car horn, then it's possible, have u considered that he may just be ignorant?

Answer 2

yes, he should be able to hear it.

Answer 3

Because your dog still has some hearing, a dog whistle will be heard since it has such high frequency- it will travel fast to its eardrums.
