I want to be able to take Maggie on walks soon. She is 4 months old and so far I dont see walking in the near future. I have tried taking her down the street and she does fine for a while. Then all of a sudden she decides she wants to chew at my ankles and feet. I eventually pick her up and take her home in my arms. I try telling her "NO" but it doesnt make a difference. Anyone have suggestions ? Is she still too young ?
