Traveling with my husband and kids.

Hi I recently was short listed to have an in person interview to teach in Abu Dhabi. While I am very excited to be considered for such an amazing job I have been looking at the private school information for my kids and they're rather expensive. What is a comfortable monthly salary for a family of 4 (me, husband, son 4yrs old, daughter 2yrs old)? My husband is not a teacher however he will want to work. Has it been easy for spouses of teachers to find employment? Also I have a small dog. What are the rules for bringing pets with you. Thanks!
