trick of the trade

Question
Hello. I am a pet sitter who's 5' tall and weighs 113 lbs. A number of my clients have two dogs, some who weigh between 65 to 75 lbs and I am often expected to walk them together. I want to feel comfortable walking two dogs of this size but right now I don't. Instead I feel nervous and overwhelmed. Is there a "trick of the trade" for a person of my weight and stature to walking two "big" dogs without feeling overpowered by the sheer weight difference? I don't want to lose any clients because of my inability to walk two big dogs at a time.
Please help and thank you.

Answer
Since I don't like to walk clients' dogs in prong collars, especially if they are reactive, my favorite is the Easy Walk Harness.  You can view them here: www.premierpet.com  There's also a fixed ring version of that harness made by another company.  It's called a Sense-ation Harness.
Halti makes a great harness, too, but I find it needs a special leash to be effective - too much expense to use it on other people's dogs.  The other no pull harness I like is the Sporn. HTH
