Village sarpanch Papa Nayak had reportedly ordered poisoning of dogs after locals complained about the dog menace. He had also received complaints of the street dogs attacking some people.
District collector Gaurav Uppal ordered an inquiry into the incident. He said action would be taken against those found guilty.
In another incident in Siddipet district, four municipal employees were suspended for their alleged involvement in the poisoning of over 70 dogs last month.
The action came after former central minister and animal rights activist Maneka Gandhi intervened in the matter on an appeal by some people.
The police also registered a case against them for cruelty to the animals.
