I know its hard with the two, but have you tried controlled crying? I know, its not for everyone, but if you think she is just crying for the sake of crying you might just want to leave her crying. You say its only for a few minutes and then she goes to sleep, she might just be crying to relieve some stress or it might help her go back to sleep. My other suggestion is to have your partner go in, my daughter is 22 months old and she is a crappy sleeper, but its even worse if I go in...so my husband goes in and that really works for her. If I go in, she wants to come in to bed with me blah blah blah...its a nightmare!
I am so sorry that she had such a terrible experience with the dog! And jetlag is a b*tch! I hope my advice can help, sometimes babies are the strangest creatures!
