Thanks everyone. I walk my dogs on a traffic lead (24 inch). Because they are older and we believe the lab that we adopted last year is most likely over 10 years old, the vet wasn't sure and the animal control facility wanted to place her desperately - crate-trained, leash-trained and housebroken so I think they really "fudged" on her age. This is really a low energy lab which works perfectly with the low energy mixed breed. Everyone said not to get a second female but this is the second time we have done that in a lifetime and it has worked fine. I've had dogs forever and always pick up after them and we have always taken long walks but the walks have grown shorter with time. I will also offer you a plastic bag if I notice that you don't seem to have one and most people are delighted to accept, it is just the sneaky ones that make a face because I caught them! I know all too well the problems that pets can create or should I say the problems that owners with pets can be.
