We bought the alleged strongest crate available, Murphy chewed his way out in 3 nights at 12 weeks old. His grandfather (Murphy I) ate the side out of a 1" marine ply kennel.
For strong, inexpensive and most importantly non-stretchy leads, try Turner Richards. They're happy to make them to specific lengths if necessary.
