It is awful that any animal has to suffer pain and starvation and live out a dreadful existent. with no contentment.
But I think that in any society where such a situation is widespread it is indicative of the history of the suffering of the people. This problem, stemming from, a nation's attitude to the care of its animals, points to a recent time of difficult existent for its people, to a time when the choice was between feeding the child or the animal.
As a county's wealth improves and people have the means to support more than their own existence they will provide more for the animal.
But it always takes time, a couple of generations before new attitudes (of how animals can and should be treated) to take effect.
Most people are inherently good. The Bulgarians in the villages see nothing wrong with how they treat their dogs because this is their understanding of the way it is done, gained from their upbringing.
Life may be better now for some and more affluent, but it will take time for them to adjust their attitudes to how they manage their dogs and elevate them in their mind to a species of higher need.
It is only when the MAJORITY of a nations people have a full belly and heat and shelter and their needs fully met, that they can became an nation of animal lovers like in the UK, where we enjoy the privilege of being in the top 10% of the worlds population, who have at least one meal a day and shelter from the elements.
It is not only the dogs in Bg who rummage in the bins to forage for food but the pensioners who have no family to support them. Not only the dogs who freeze in winter but the children in the orphanages,
It is not an education in the care of their dogs that this nation needs but an eradication of the memory of the suffering of its people and then care of the animals will follow.
Widespread lack of basic animal care, I feel is founded in the suffering of people, and human poverty is never far away.
