Coolie Pup Flying Overseas

[Ons]

I've got a coolie pup since Sunday who is 4 months and 4 days (I have her litter mate) staying this week with me. She is flying overseas on Friday to Canada, such a long way for a little girl to go but she is going to the bestest of best homes over there and the people already have some coolies imported from Australia.

Is there anything I can do though to make her journey a bit more comfortable?

anything I could be teaching her.

I've been crate training her this week in that she sleeps in a crate at night with my pup although I've been leaving her in there for a couple of hours on her own, and when I've gone out I've left her in there. She is beginning to protest less.

and she doesn't have a collar on. Should I get one, get her used to it this week and send her off wearing one or leave it?

thank you
