Does anyone on the WZ know how to tell when a dog has AMS?
Lynn, this is not a joke, but I would think "Mountaineer's Foot" applies to pets as well, ie, can't put one foot in front of the other...then go down.
Different species of animals have different pulmonary vasculature reactivity to hypoxia. Cattle are very sensitive even to 7,000 ft. See Brisket Disease (Chronic Mountain sickness in cattle). Don't know about dogs (or pigs)
