Thank you for all your suggestions. I am note sure the metal fence will hold him. He is so big!
Last summer we went to Paris on vacation and on the way back, our flight got delayed and we had to make an medical emergency stop at JFK. Then our flight had to wait about 2 hours for clearance to land in Atlanta. Drake was in the crate all that time and when we got home, he was so mad and angry. He growled at everyone, including Andrew and I, for two weeks. Would not let anyone near him. Ever since then, he will no come close to the crate. We wanted to take him wih us to Pennsylvania for 4th of July, but we couldn't fly coz he wouldn't get in his crate. We had to drive!
So, I do not think i will be able to crate him. I will try the doggy door though!
