The BBC’s Victoria Derbyshire programme is looking at the dogs who are being trained to be aggressive and dangerous to humans.
“They’re not going to be any fun to live with, you know,” says one of the trainers, Dr Paul Taylor, a professor of veterinary psychology at the University of Bath.
When he’s working with the dogs, he says, the aim is to make them feel like they’re being watched.
Dr Taylor says the first step is to get them used to their new surroundings, to learn how to walk on a leash and how to greet visitors.
Once they have a sense of how to behave, Dr Taylor says, they can learn to behave appropriately to strangers, and in some cases to strangers in the future.
One of the first trainers to come to the rescue was a Labrador retriever called Daphne, who became so good at walking on a walker that she became the most popular of the dogs.
A year ago, Dr Tayler and his colleague Dr Tim Trewavas had Daph.
The first time Daph was seen outside, she began running up to the man who was watching her.
After he saw her, the man said: “I think I’ve seen the first dog.”
Dr Tayler says Daph is a great example of the way in which dogs learn to associate humans with safety.
“She’s not a dog that’s going to run away from you, she’s going through a phase where she’s very trusting,” he says.
“And then, of course, when she sees that she has a human, she reacts by jumping in.”
The problem with being a Christmas dog, however, is that dogs can become overly protective.
Daph, for example, is now used to being left alone in her own home.
And she can also get too used to her new surroundings.
But she has learned to be more confident about her safety.
This has led to a couple of incidents, such as when she was called to a park by a man she was looking after, but when she arrived she was startled by a large dog.
She started barking at him and then ran off.
In one case, a dog ran into a man who had been walking his dog.
The dog was then chased by the man and ended up killing him.
Another time, Daph and her friend, Daisy, were chased by a dog.
When they got to the foot of a tree, the dog bit Daph on the leg, injuring her and leaving Daisy severely injured.
They had to be put down.
For Dr Taylor, the most important lesson for the dogs is that they need to learn to trust people.
While he believes that the training of dogs is a positive process, Dr Dabrosi says it is not enough.
Because the training process involves a large number of dogs, there are some who are not ready to accept the concept of being trained.
It’s a question of training time, he argues.
That’s where Daph, Daisy and Daphane come in.
“We do need to train these dogs to be comfortable with themselves and their behaviour.”
It’s about not allowing them to feel that they’re unsafe or that they should just run away,” Dr Dabsi says.
You need to be in their face and in their head,” he adds.
Many of the dog training programmes run by Dr Dapsi and Dr Taylor also involve the training and teaching of other animals.
So, for instance, Dr Trewa says he and his partner were keen to train a puppy.
We’ve seen an amazing amount of positive results with dogs that are trained,” he explains.
At first, the puppy was terrified and was very scared of people, but the trainers learned to let her trust them.
As the puppy grew, she became more and more comfortable around humans.
But Dr Taylor and Dr Dubs say they have found that a dog can be trained to become aggressive to strangers without having to have to teach it how to treat people first.
He says that when the dog is allowed to learn about other people, it becomes very social and friendly.
Other dogs can also be trained and trained to behave in a particular way, for other reasons, and these dogs can sometimes become very dangerous to people.
Dr Taylors work with other dogs, too, including the Labrador retrivers, but he also has his eye on a new breed of dog called the miniature cross.
Dr Taylor and his team have been working with two dogs, one of which is a small cross called the Staggies, who were trained by Dr Taylants group.
I think a lot of people think that these dogs are just going to jump up and down in front of humans, and they’re not,” he tells Victoria Derby.
Well, it’s actually very difficult for them
