article: Leaving a favourite dog in kennels while travelling abroad can be a source of profound guilt. But one owner was so overwhelmed with anxiety at the thought of being parted from her pet, she decided to take the dog on her frequent journeys overseas. As a result, May Wong’s four-year-old cockapoo, Miss Darcy, has travelled the globe - visiting 11 countries and 23 destinations including New York, Berlin, Stockholm, Milan and Paris. She takes more trips with her owner every year than the average Briton and has covered nearly 25,000 miles since 2011 - making her a real-life Phileas Dog. Scroll down for video . C'est la vie!

Seasoned traveller: Cockapoo Darcy in shades as she takes in the sun in Nice in the south of France . Now the pair have been joined on their trips by Miss Wong’s new dog, George. The dogs have travelled on planes, trains, cars and ferries across the world and sleep in dog-friendly hotels with their 55-year-old-owner. Among the landmarks they have visited are the Eiffel Tower, New York’s Central Park and the Berlin Wall. Miss Darcy, who took 12 trips with her owner last year alone, has become such a seasoned traveller she is familiar with boarding procedures at stations and airports. Her interior designer owner said: ‘Over time and effort, travelling with Darcy has become routine. ‘I know her ways and by now she’s familiar with being in trains, waiting around in stations, boarding procedures for ferries and planes. She is a very calm dog. I am lucky that she is a very good traveller. Boat trip: Darcy with her owner May Wong on board the Queen Mary in the Atlantic returning from New York . ‘My dogs are my best friends, my family – and I enjoy exploring places with them. Having them with me makes me more relaxed during my holidays rather than thinking about them and worrying if they are okay.’ Research from pet insurer Petplan has found that 65 per cent of people experience separation anxiety from their pets when holidaying - something which Miss Wong has struggled with. She tried leaving her dogs with friends, dog trainers and kennels but felt distressed by finding them unhappy and, on occasions, unwashed, on her return. Miss Wong, from London, said: ‘On occasions when I had left Miss Darcy behind with friends, she’s constantly on the lookout for me when she was out walking. She was restless and listening out for me all the time, whining, which is out of character for her. ‘They may not necessarily appreciate the effort I go through to have them travel with me but I know they would rather be with me than not.’ Before going abroad, Miss Wong researches dog-friendly hotels and restaurants so she can eat and sleep with her dogs. She said: ‘We’ve travelled by rail, car, plane and ferry. Being checked into cargo on a plane is not the most pleasant way for pets to get places. I would do so only if it is absolutely necessary in order to get my pets to where I will be if I am gone for long periods.

Pictured: On a train before arriving in Bruges, Belgium . ‘I am most concerned about their comfort level and have restricted our vacations to places where I can take them and where it is safe for them to go to. ‘There are obviously occasions where I need to travel further afield and that are not worth risking their safety to bring them along.’ Inga MacKellar, Petplan’s pet behaviourist, said pet separation anxiety can be felt by both pet owners and their animals. She said: ‘Dogs are as social a species as we are, so it is not surprising that some dogs can’t cope with being left by themselves. ‘On the other hand, we know that cats are a solitary species and many like to spend time on their own - however, whilst most separation problems are usually seen in dogs, it doesn’t mean that all cats are happy to accept being alone. ‘Some can become over attached to their owners and also suffer from separation problems. ‘Separation anxiety can vary in intensity, with signs including restlessness and panting, howling, destruction or messing. ‘Knowing that 65 per cent of pet owners experience separation anxiety themselves when leaving their pets, with symptoms including uneasiness or restlessness, it’s evident how much our pets mean to us.’ Well travelled: Darcy's pet passport .
