Why do Romanians not nuture there dogs

From my experience, the decision not to sterilize (neuter/spay) animals is based on a lack of education of the benefits involved which you mentioned in part, as well as cost which you mention (though it doesn't cost very much IMO).  I've also encountered several older-age vets which refused to sterilize animals until they reach 1 year of age, claiming health risks, which is simply nonsense.  Again there's a lack of proper education and awareness of practices outside Romania, at least among the older vets.  The younger docs I've met seem to have a better understanding.

This creates a big problem as you've noticed, many feral or semi-feral animals on the street which reproduce regularly, exponentially increasing the population. The animal control organizations of cities often cannot keep up with rounding them up and supporting the cost of sterilization, tagging, or sheltering.  Also they have to deal with the "animal rights" activists which get angry anytime a city goes around rounding up the animals; even though children get bitten and even killed each year by street dogs.

As a responsible pet owner myself, I'd really like to see the implementation of animal licensing, mandatory microchipping, vaccinations and sterilizations.  Owners need to be held accountable for their part in this, but they also need to be properly educated about the issue.  It's unlikely to happen I think, as it would require countless commissions, debates and other bureaucratic nonsense.  I think many would moan about yet more requirements being put onto them, as usually happens when change is implemented.

As with most things here, this is part of life here, take it or leave it.
