Thanks - will find a bottle - considering winter's coming and she'll be 16 weeks in November we won't be having long walks for a while - but it's useful to get an idea of distances and water needs.
On the other hand, I wonder if I can get this in Yorkie size once she's more grown up and the days get warmer?
