Flying dog earns her crew card!

With so much airtime, I wonder if Callie's owner can give some assessment if her hearing has been impacted. We take our dogs on flights, in unpressurized SEL aircraft, with dB levels ranging from 88-93. We have bought both of the major brands of dog hearing protection. In spite of the promotion material, neither have resisted the dogs ability remove them.
Thus, I am reticent to subject them to frequent flights and on-line searches and veterinary consults have not provided concrete-verifiable data.

Congrats to Callie.
