Re: Does the altitude affect a dog's hearing?

Dogs have a wider range of hearing than humans but essentially the 
physiology is the same. We compensate for pressure in the inner ear as we 
move to higher altitudes. This would also happen for dogs. 

The question as to whether the less dense atmosphere at higher altitude 
effects sound transportation and to what degree is a higher order physics 
question which I am unable to answer. 

You might like to rephrase the question and ask it again. 

Perhaps: "Does the lower air density a higher altitude effect sound 
tranportation and how does this effect hearing in dogs?"

Best of luck. Cheers Royce www.funshow.com.au
