A sudden surge in dog bites has put Kalyan on alert, with more than 250 cases reportedly recorded in just 48 hours. The sharp rise has hit several busy areas, including around Kalyan railway station and Rukminibai Hospital, although official figures vary and authorities are still collecting data to establish the true scale. With more than 80,000 stray dogs estimated across Kalyan-Dombivli, the civic body is expanding dog-catching operations, identifying hotspots and accelerating sterilisation efforts. What caused such a dramatic spike remains unclear - and that may be the most worrying part.
