<human>: HI there! I hope you can help me with a question I have. Recently my parents booked a flight with Lufthansa but they booked the pet tickets for cargo.
One of my dogs is 6 kg, so I told them they should call lufthansa and tell them that one dog is going in cabin and the other one is going in cargo.
The problem is that the 6 kg dog is taller than what they allow to go in cabin- even though she is less than 8 kgs. I dont think this should be a problem because they are travelling in business class and I know they have more leg space, so a slightly bigger dog should be allowed if it is less than 8 kilos.

My concern is: if I call lufthansa, tell them my dog will be in cabin but then in the airport they think it is too big...can my dog still travel in cargo? or does she lose her booked place completely? If a dog is rejected for traveling in cabin, can it still go in cargo and can that change be made the same day of the flight?
or do I need to know in advance if they dog will go in cabin or cargo? because I really cant know until the very day and Im anxious about it.

I hope someone else who has had the same can enlighten me . Thanks a lot!

Can you give me the gist of the text in a nutshell?
<bot>: Can you say a dog flies in cabin and if it isnt accepted because it is too big, can you still send it in cargo?
