Absolutely brilliant advice mate. Been camping nearly every other weekend since I was 2 weeks old and we always had dogs growing up but I’ve now got three of my own and it’s been a while since I’ve been camping sadly. Our old boy is getting near to the end of his time with us and we’re planning to do a camping trip from SA all the way to the snow so he can see snow for the first time ever. We’ve got 2 Australian cattle dogs and 1 border collie 😅 (We muzzle and crate train our dogs just to keep them safe) one of my dogs chewed through the leash you suggested…twice 😂 we made our own leashes with chain from Bunnings, some clips and the chain carabiners
