I have three dogs. I walk them seperately. The two girls can be walked together however in a mult dog house I try to give everyone some individualized attention.(the building the relationship vs getting too doggy) Mine all seem to pull more when not alone.The biggest drawback to that is time . I'd probably want to be able to help them learn to walk together as it increases yours and their oppurtunities for social oppurtunities.
