As of early December, there is still a lot of speculation as to the cause of the respiratory infection. At this point in time, there have been no definitive causative agents identified - it is not known if it is bacterial or viral or both. We know of no reported cases in NJ, but it's in Florida, Maryland, Virginia, New Hampshire and Vermont as well as the west coast, so it's just a matter of time.

It looks and acts like kennel cough, but it doesn't respond to our usual treatments. It starts out as a runny nose and/or eyes and a cough develops. In some dogs, it can progress to pneumonia in a day or two and others it just causes a cough that lingers for weeks to months. We have a lot of good respiratory tests available these days and there is no one common organism that is being isolated in the dogs who have become sick. There is a recent report that a group of researchers in New Hampshire isolated some kind of "micro" bacterial organism, but we don't know whether or not it's the whole story. If it's viral, it will likely be difficult to isolate as once dogs are sick, their viral load goes down which means not as much virus is shed which makes it difficult to isolate. 
For right now the recommendation is to make sure dogs have updated respiratory vaccinations (Bordetella, Parainfluenza, Adenovirus, Canine Influenza) and to avoid gatherings of dogs (parks, kennels, day cares, etc.). It is not yet known if vaccinations will provide any cross protection, but it will help to ensure they maintain a healthy immune system.

If you are not sure of your dog's vaccination status or would like to schedule an appointment, please call (732-356-9889) or email us (

Our office is now fully OPEN, but we are still offering curbside service for those who would like it.

Everyone is welcome to come in the building, but we are limiting the number of people allowed in the exam rooms. Only one person at a time in the exam room with your pet.

We strongly recommend everyone wear a mask when coming in our building.

 We will continue to have the PICK UP BOX. It is located to the RIGHT of the planter as you face the building-there is a sign on the building pointing to it.

If you are dropping anything off, please use the Idexx Lab Box which is to the LEFT of the planter as you face the building. Please call and let us know you left something in the Idexx Lab Box so we can bring it inside the building.

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.
