Absolutely

I have used one in the past with my 2 BT's and it worked well. But if I am honest I prefer 2 leads just for the simple reason that I like my dogs to have a bit of independance with they don't get if they are attached to each other

These two I'll add are known to be pains in the neck around here in terms of barging up to other dogs and generally not listening to anything and were not a happy pair, over each other, around each other, getting smacked (yep not joking ) for being the furry tornado - can't help but think she'd do better having them on separate leads in her case.

I use one, or a double ended lead, when we are on holiday.
It's easier than trying to hold 4 seperate leads & pick up poo, open gates etc.
