Yes unless it doesn't have metal but on some airlines they do but during airport security check you can't but some airlines give you leashes
I saw a dog on a leash going through security check... He had a chain collar because he was a husky. I'm pretty sure you can... not positive though.
Depends on the current policies of the specific airport, according to me. Kindly call & check up before leaving your house
You can. There are also dog areas outside the main terminal.
Dude yes you can but some airport they do not need dogs but some times it depend's in how you on your Cargo you have.
