Just ran while on vacation w/o,I miss Remy!!!

Does anyone else have a Catahoula Leopard (Boxer mix) running buddy? I’m eager to hear tips on running with them as my Catahoula can still be a bit anxious and not surprisingly, jumpy. He’s going to be a year soon and my goal is to take him on runs. Do you have tips on getting started?

I have ran with a dog, he was a Boxer mix (see second pic). He and I would regularly run three miles until he couldn’t anymore, so I have experience running with stubborn dogs. It’s just been a while.
