January splits Europe into two dog-friendly regimes. Head to Lisbon or Porto for mild Atlantic days near 14-15°C, dog-accessible beaches year-round, and none of the summer heat risk. Or lean into deep winter: Vienna, Berlin and Innsbruck reward dogs with heated trams, cosy cafes and quiet snowy parks, while Reykjavik offers peak Northern Lights and near-permanent dusk for a completely different kind of trip.
Pack a coat for anything below 10°C, in short for Vienna, Berlin, Innsbruck and Reykjavik. Post-Christmas calm means shorter queues, lower prices and calmer streets everywhere on this list, a genuine bonus for a dog that dislikes crowds.
⚠️Good to know: Below 10°C, Vienna, Berlin, Innsbruck and Reykjavik all call for a coat and paw protection on ice and salted pavements.
