How Long Can A Dog Hold Its Breath?

i am going to try and be as civil as possible. do not ever put any animal, especially puppies in a box to send them, even as a gift. first of all, they cannot hold their breath as we can, secondly heat is even more dangerous to them. rather go and deliver the puppy yourself or ask someone to do it for you. i will appreciate it, if you do it this way. NO BOX, whatsoever. if you open the box and the puppy is still, get luke warm water and wet it, then you give that puppy water as fast as possible. then you go to a vet and let them have a look. PLEASE do not ever do that again.
