This guy is an idiot... If he knew anything about diving, he would know the potential risks and the physiology applies to animals as well. He can't possibly know how nitrogen builds in his pets' bodies and what it might do to them. Dive tables, profiles and ascent rates don't apply to them. Besides, they are dogs and cats- they can't possibly understand or enjoy what's being done to them. This guy is a selfish, stupid idiot!!!
