Note that the completion of vaccinations and vet forms can take 3-4 months, so if you want to take your dog to Denmark, plan early. Tattooed dogs and cats won't qualify after 2011 in favor of microchips.
The most important thing to know when taking your dog to Denmark is that two types of pet regulations exist depending on whether you enter Denmark from an EU country or from a non-EU country. The Danish Department of Agriculture provides a guide as well.
Bringing your dog to Denmark from the EU: First of all, get a EU pet passport from your vet. Your licensed veterinarian will be able to fill out the EU pet passport as required. To take dogs to Denmark from within the EU, the dog must have be vaccinated for rabies at least 21 days prior to traveling, have a microchip (tattoo acceptable), and the EU pet passport. You can enter through any Danish border crossing.
Bringing your dog to Denmark from a non-EU country: Requirements for pet travel are slightly stricter. Like travelers from the EU, you should also get your dog a pet passport if at all possible or have your vet complete the Veterinary Certificate (.doc).
In addition, you will also need to notify the Border Inspection Post of your intention to travel to Denmark with your dog (or other pet) at least 24 hours in advance. Any dogs, cats and ferrets from third countries must come into Denmark on flights to Copenhagen Kastrup Airport or flights to Billund Airport.
Taking your dog to Denmark from a non-EU country also requires the dog (or cat) to be vaccinated for rabies at least 21 days before traveling to Denmark.
When you arrive in Denmark with your dog, enter customs and request a pet inspection. Danish customs personnel will help you with the process and will check the dog's (or cat's) papers.
Tip for booking your dog's flight: When you book your flights to Denmark, don't forget to notify your airline that you wish to take your cat or dog to Denmark with you. They will check for room and there will be a one-way charge. (If you wish to sedate your pet for the trip, ask whether the airline's animal transportation rules allow this.)
Please note that Denmark renews animal import regulations annually. By the time you travel, there may be slight procedural changes for dogs. Always check for official updates before taking your dog to Denmark.
