• Adopt A Dog Puttin’ on the Dog Canceled for Sept 27
Note: Adopt A Dog has decided to cancel Puttin’ On The Dog, scheduled for Sunday, September 27. With a Nor’easter expected to bring high winds and significant coastal flooding, the safety of our dogs, guests, volunteers, vendors, sponsors, and staff must come first.
Puttin’ On The Dog is Adopt-A-Dog’s largest fundraiser of the year, providing critical support for the food, shelter, medical care, training, and enrichment our dogs need while they wait for loving homes. Although the event cannot go forward, that work continues every day.
Anyone who purchased tickets in advance, Adopt A Dog will send them a charitable contribution receipt for their records. Anyone who had intended to buy tickets at the gate, please consider donating an amount equal to the planned ticket purchase. Your support will help ensure that, even though Puttin’ On The Dog cannot take place this year, the dogs who depend on us will continue to receive the care they need.
Your generosity would help mitigate the significant impact of this cancellation and ensure that the funds from your ticket go directly toward caring for the dogs who depend on us. Adopt A Dog will gladly provide a charitable contribution acknowledgment for your records.
Half Marathon
An important update regarding the Greenwich Half Marathon. After careful consideration & consultation with Town officials, the Greenwich Road Runners have made the difficult decision to postpone Sunday’s race due to the forecast for high winds, potential coastal flooding, power outages, & fallen trees & power lines.
The race has been rescheduled for Sunday, October 18.
The safety of our runners, volunteers, spectators, & the community remains our highest priority. While we are disappointed to postpone the event, we believe this is the right decision given the expected conditions.
All registered participants will automatically be transferred to the new race date. Participants who are unable to attend on October 18 may defer their registration to the 2027 race.
If anyone had planned to run on September 27 but was not previously able to register, we still have spots available for October 18 & would be delighted to welcome additional runners.
