I have both! LOL OC is trained to walk on my left side and Ronan is trained to walk on my right so when I have both I have a dog in each hand. Makes controling them much easier than having both in one hand. Ronan will flip to either side without any issues. If I walk OC on the right he tends to pull a bit though and doesn't quite grasp the concept to stay back at my side. That's not him though, that's me not bothering to take the time to solidify that part in his training
