From an idea, to a concept on paper, to house calls when our building wasn't as ready as we were, to finally opening the doors in 2018. Through a pandemic and all the ups and downs of starting a business, we are thrilled to be celebrating our 5 year anniversary! VHCG has grown into a thriving team of dedicated, highly skilled, and compassionate members. We are so proud to be a part of this wonderful community. Thank you to all of our valued clients who have entrusted us with your pet's care. We look forward to many more years of working together to keep your pets healthy and happy!

COVID-19 Protocols

COVID 19 Mask

For the safety of our clients & staff at VHCG, we have put in place COVID-19 protocols as follows:

- We request all clients wear a mask during their time in the examination room.
- Please DO NOT enter the clinic if you are showing any signs of illness (fever, coughing, sneezing), have tested positive for Covid, or have had possible exposure to Covid within the past 14 days.
- Due to the small exam room size and our continued desire to practice effective social distancing, we request only one client be in the exam room.  If more than one person is in the room, one person may be asked to step out into the lobby, or their pet may be brought out back to be examined and treatments performed.
- If you prefer curbside service, please call the office when you arrive (978-448-5100) and a technician will come out to your car.
- We recommend using our online store for refills of food and medication.
- If you have questions about your pet’s health, you can always call our office before coming in, and we can work with you to decide if a visit is necessary.
- We reserve the right to decline entry to the building or to ask any client to wait in their vehicle if you are showing signs of illness.
- If necessary, we will happily reschedule your appointment for another date and time.

Please do not hesitate to contact our office if you have any questions or concerns. We thank you for your business and cooperation with these guidelines, and hope everyone stays healthy.

Cancellation Policy

To ensure the smooth functioning of our services, we kindly request that you inform our office of any cancellations or rescheduling at least 24 business hours prior to your pet's scheduled appointment. A $35 fee will be applied for all No Show appointments or those canceled or rescheduled with less than 24 hours' notice.

For surgical and dental procedures, we appreciate a minimum of 48 hours' notice for cancellations or rescheduling to avoid incurring a cancellation fee. A fee equivalent to 10% of the estimated procedure cost will be charged for all No Show procedures or those canceled or rescheduled with less than 48 hours' notice.

In the event of repeated cancellations and no-shows, a reservation fee will be required at the time of scheduling appointments and procedures. As a privately-owned small business, these policies are in place to mitigate the significant impact that no-shows and cancellations can have on our operations. Your understanding is greatly appreciated. Thank you.
