hmmm....I bought a crate for our aussie for strictly travelling purposes. She is 3 years old... and was never crate trained. She has flown 3 x now and seems to get worse each time. The last time I had to actually push her into the crate at the airport. She doesn't whine, she just looks at me like I'm the worst mom! So I've been trying to get her a little more familiar with the crate at home. She knows now that everytime she goes in the crate and lays down, she gets a treat. It's probably not really the crate that is the problem.. its the flying, I'm not sure. I keep trying though because its either a short 1 hour flight... or a boarding kennel.
