I think i know the dog Tinkerman is talking about - she has been adopted by a friend of mine. Maisey (the dog) is the sweetest thing you could ever come across and already follows my friend everywhere. She has an amazing temperment.
When I left the Middle East, due to where I lived, i had 4 flights over 2 days. Never once did i consider leaving my cat behind. She had never been on an aeroplane before but coped very well. Like many people on the forum, i have no understanding of people who are so willing to just desert their pets. You make provisions for them and show them the loyalty and love they show you.
