Thommo's new collar and lead are from Rogz for Dogz - from the Beach Bum range for large dogs, his pattern is Surf Saint Patch. The guys behind Rogz have a background in extreme sports and it shows in their great range of patterns and fun online catalogue. I found mine in the local PetBarn but they are available from a number on online stores in Aus.
Features I like include contoured plastic components for a comfortable fit, a breakaway clip for when the dogs are home alone is lockable for when you don't want it to suddenly come undone, a leash clip ring that is mounted in a way that limits strain on the clasp, and a reflective thread woven into the webbing.
Besides, as it says on the site, these outfits have some serious mojo.
