I had read quite a few threads about whether to walk or not and am still unsure. There is one area around here that is usually very empty of other dogs and if I get the timing right I hopefully won't see anyone at all but she is a little dog (Parson Russell Terrier) and I suppose I am very nervous of another dog jumping on her and me not being able to get the dog off. Would putting a nappy on her stop the smell or not?
