Local mayors who do not enforce the law could be put in prison for two years.
Turkey has approved the "massacre law" as it has been dubbed by animal rights activists and opposition lawmakers.
It will see millions of stray dogs removed from Turkey's streets, with President Recep Tayyip Erdogan saying the new is necessary to deal with the country’s “stray dog problem.”
Animal lovers fear it will lead to many of the dogs being killed or ending up in neglected, overcrowded shelters.
Humane Society International said it had written to Erdogan to raise concerns that the law will cause “unnecessary suffering and death to countless animals in a short-term fix that won’t deliver a long-term solution.”
The government estimates that around 4 million stray dogs roam Turkey’s streets and rural areas. Although many are harmless, a growing number are congregating in packs, and several people have been attacked. The country’s large stray cat population is not a focus of the bill.
What is Turkey's new stray dog law?
The new legislation requires municipalities to collect stray dogs and house them in shelters to be vaccinated, neutered and spayed before making them available for adoption. Dogs that are in pain, terminally ill, or pose a health risk to humans will be euthanised.
However, many question where cash-strapped municipalities would find the money to build the necessary extra shelters.
“Since there are not enough places in the shelters — there are very few shelters in Turkey — a path has been opened for the killing (of strays),” said veterinarian Turkan Ceylan. “We animal rights activists know very well that this spells death.”
'Your massacre law is just a piece of paper for us'
In Istanbul’s Sishane Square, hundreds gathered and issued a defiant message to the government. “Your massacre law is just a piece of paper for us,” the organizers told the crowd. “We will write the law on the streets. Life and solidarity, not hatred and hostility, will win.”
Animal lovers in the capital Ankara protested outside municipal offices. To whistles and jeers, a statement was read: “We are warning the government again and again, stop the law. Do not commit this crime against this country.”
Protests organised by political parties and animal welfare groups were also held in cities across Europe, where there were warnings the law could dissuade tourists from visiting Turkey.
Turkey's main opposition party said it would seek its cancellation at the country's Supreme Court.
“You have made a law that is morally, conscientiously and legally broken. You cannot wash your hands of blood,” Murat Emir, a senior deputy with the Republican People’s Party, or CHP, said on Sunday night in parliament. He questioned why the bill called for healthy and unaggressive animals to be collected if they were not to be killed.
Others blamed a failure to implement previous regulations, which required stray dogs to be caught, neutered, spayed and returned to where they were found, had led to the growth in the canine population.
Main opposition party says it will not implement the law
The CHP, which won many of Turkey’s biggest municipalities in elections earlier this year, has said it will not implement the law.
However, the newly passed bill introduces prison sentences of up to two years for mayors who do not carry out their duties to tackle strays, leading to suspicions that the law will be used to go after opposition mayors.
Ali Ozkaya, of Erdogan’s Justice and Development Party, or AKP, described the bill as a “demand of the nation.”
The government denies the bill would lead to a widespread culling. Justice Minister Yilmaz Tunc told journalists last week that anyone killing strays “for no reason” would be punished.
Murat Pinar, who heads an association campaigning for measures to keep the streets safe from stray dogs, says at least 75 people, including 44 children, were killed as a result of attacks or by traffic accidents caused by dogs since 2022. That’s the year his 9-year-old daughter, Mahra, was run over by a truck after she fled from two aggressive dogs.
During public meetings on the bill, representatives of some nongovernmental groups were prevented from observing the proceedings.
