OVID-19 Curbside update

COVID-19  Curbside Appointment Update -June 2021

We will be implementing new protocols for our Social Distance Appointments and escorting one client inside with their pet beginning June 1st.  Due to the limited space in our lobby and our exam rooms, some appointments will remain by Curbside at this time.

Social Distance appointments will include, but are not limited to, most examinations for ill or injured pets and pets receiving wellness vaccinations.
We will confirm if your pet has a Social Distance Appointment or a Curbside Appointment when you schedule your pet's appointment or when you check in.  Please continue to call when you arrive.  This will allow us to prepare a sanitized room for you and your pet.

We will continue to offer Curbside Appointments to all of our clients and would be happy to escort your pet inside if you prefer.  This is a good option if you would rather wait in your vehicle, have children with you or if you just want to come as you are and stay in your car!

As much as we would all love to see every single one of our clients again, refills of prescriptions, food and supplies, as well as some appointments, will continue by Curbside at this time, due to the limited space in our building.

Please inform us of any COVID-19 exposure, symptoms or positive test in the past two weeks, so we can make alternate arrangements for your pet.

To help minimize exposure between staff and clients, we will ask that one person only escort your pet inside.  At this time, masks will be required for all clients, regardless of vaccination status.  Our goal is to keep our staff and our clients healthy and safe while we continue to provide your pet with the health care that they deserve.  

Your continued understanding and patience is greatly appreciated as we navigate through our new protocol changes.  These changes may increase waiting times.  

Thank you for allowing us to be part of your pet's Health Care Team.

If you have any questions, please feel free to reach out to us.

PLEASE NOTE:  For the safety of your pets,  ALL cats must be brought in a secure carrier.  If you do not have a carrier, we are happy to loan you one.  ALL dogs must be brought on a non-flex leash and a securely fitted collar or harness.  We will be escorting our dog patients with our slip leads as well.  Small dogs and other small pets can also be brought in a secure carrier.

If your pet needs a refill of medications, supplements, preventions or prescription diets, we have a few options to help you receive these necessities for your furry family members:

🐾 My Vetstore! Most of the products that we carry here in our hospital are also available on our Online Pharmacy: https://northshoreah.myvetstor...

🐾 Curbside! Order your prescriptions like you always have. Call us when you get here. We will  bring out your pet’s medications, food and anything that you and your pet needs while you wait in your vehicle.

🐾 Home Delivery! For our senior, quarantined and at-risk clients, one of our staff members will deliver what your pet needs, right to your front door for porch pick-up.

We want our clients and patients to stay healthy.  We hope these options will alleviate some of the stress and worry that you may have regarding your well being  as well as your pet's health care needs.
