Many dog owners aim to raise a well-behaved and calm pooch while maintaining the dogs personality, but that doesn't always go to plan.
Some dogs, such as huskies, beagles and lurchers, can be tricky to train, while other pups may just be naturally stubborn - whatever the breed. Owners may get to the point where they feel they've tried everything, but a dog training specialist has advised owners what to do before they get to this point.
Wendy Kruger, dog behaviour and training specialist at Woodgreen Pets Charity, where Channel 4's The Dog House is filmed, says owners should seek help as soon as they notice a problem with the dog.
