Is the cargo hold of a passenger plane pressurized?

Are all cargo holds the same, or does it depend on the make/airline of the plane? No guesses please.Is the cargo hold of a passenger plane pressurized?
All cargo holds are not the same...Some are pressurized and some are not. Some aircraft have pressure in the forward baggage hold, but not the back. It depends on the plane you are flying in. As for being able to carry dogs, you are not able to carry dogs in all aircraft.Is the cargo hold of a passenger plane pressurized?
It is pressurized, but the heat is normally only turned on if they are shipping animals.
Yes,





And also, it is heated. Climbing up to altitude it has to be. Its just a little cold at FL 36,000ft.
yes or they would not ship animals
I don't think the main cargo hold is. But there is a small hold in the front where animals and special cargo goes that is pressurized.
