Typical cobblers from an operator worried about the costs of any potential lawsuit for carriage of animals other than pure domestic pets. I've dispatched numerous scarebus flights off to warmer climes with an old biddy's cats in the hold. Don't see why a dog would be any more vulnerable given the hold can be heated and pressurised.
The trick is putting the beasts on the correct aircraft. That way old biddy doesn't arrive in Alicante to find her now dead cats have actually been sent to Tenerife.
