Due to the corona virus outbreak, we ask that if you or anyone in your house hold is sick, if you have traveled out of the state in the last 60 days or if someone new has come into your home (parents, kids home from college, friends, relatives, etc.) that you let us know so that we can continue to take the proper precautions to ensure the safety of our clients and our staff.

Effective immediately the FRONT DOOR WILL BE LOCKED WHEN YOU COME. Please call 732-356-9889 and leave a message or text 609-759-1507 (Google Voice) when you get here and someone will come out to help you. Please be patient during this time, we will get to you as quickly as we can. Thank you for your patience and your understanding during this "new normal".


If you feel your pet needs medical care but you or someone in your family isn't feeling well or you aren't comfortable coming to the office, you can set up a telemedicine consultation services through our app or copy and paste:

Scroll down and choose "Schedule Virtual Exam"  and follow the prompts. Please call our regular number (732) 356-9889 if you are having any issues. Please leave a message with your name, your pet's name and that you want to set up a virtual exam. We will return your call and help you. If Dr. feels she needs a "hands on exam" or testing, we will do our best to accommodate each individual on a case by case basis. We are prepared to bring your pet into our office while you wait in the car. The Dr. will call you during the exam. If medication is needed, we can deliver it to the car or we offer a home delivery option.

Please note that the telemedicine consultation service is for our current patients only. During the coronavirus pandemic we are offering a reduced office exam fee in order to help with the financial stress many of us are dealing with.

As of this time, there is no evidence that our pets can transmit COVID-19 to us but we can infect them. Our lab is prepared to start testing with a PCR test should this situation change.

We are also pleased to now offer a 24/7 triage service sponsored with us by Royal Canin. You will be connected with veterinarians who will be able to provide guidance after hours but will not be able to prescribe or treat your pet. They will email us with their findings so we can follow up with you when we are available. Please copy and paste: or to start a pet chat text vetnow to 67076.

WHAT IS A CORONAVIRUS? Coronaviruses are a large family of viruses consisting of multiple subgroups of viruses that are commonly found in humans as well as other mammals, birds and reptiles. Coronaviruses get their name from their spiked surface proteins, or corona, which is Latin for crown. Coronavirus infections in animals, for example feline enteric coronavirus, are commonly alpha coronaviruses.    The SARS-CoV-2 virus, which causes Coronavirus disease 2019 (COVID-19), is a unique coronavirus that infects the human respiratory tract and is different from previously identified coronaviruses infecting humans or veterinary patients. SARS-CoV-2 causes COVID-19 respiratory disease in humans and is a beta coronavirus. COVID-19 was first detected in China with an initial outbreak in the city of Wuhan. SARS-CoV-2 is believed to have originated from bats. Since its emergence in late 2019, COVID-19 has spread to locations around the globe, including the United States. (Adapted from Idexx Laboratories)
