I walk everywhere too and always take Mika everywhere I can. When we first brought her home before she had her jabs I used to take her out in a hotdog bag (the type that has a hole in one end so your your pooch can look around) I always have a pram with me too as I have young children and I w ould hang the bag on there. Its not a very common sight in the UK (esp where I live) to see a dog in a bag so I would get alot of comments but never anything nasty. As she got bigger and finished her jabs she started to walk more and more and now she keeps up with us all day long (if she does get a little pooped she hops on the bottom of the pushchair
)!
