Proheart 12 now available!

Have you ever missed a dose of your dog's heartworm prevention?  Do you have a hard time remembering to give it every month?  If so, Proheart 12 may be something to ask your veterinarian about. ProHeart 12 is a veterinarian-administered injectable heartworm preventive for dogs over the age of 1year that provides 12 months of heartworm disease prevention eliminating the need for monthly dosing.  Though used in Australia since 2000, it was just approved by the FDA for use in the United States.  We now have this product available.  Please give us a call if you are interested.

FREE Dental Examinations Available!

Did you know we offer complimentary dental evaluations for your pet? This is a brief, focused examination of your pet’s oral health. If a dental cleaning is scheduled at the time of the dental evaluation or at the time of your pet’s regular wellness examination, you will receive a 10% discount on their dental procedure.  New and existing clients welcome.

Please call the office (301-774-9500) to schedule an appointment for your pet.

OSSVH has a new partner in pet care!

As pet parents, we know that you want to do what is best for your pet and to help, we are now offering Trupanion Express.  When you have Trupanion pet insurance and your pet comes in for an accident or illness, we submit the insurance claim on your behalf and Trupanion gives us a decision within five minutes on the amount they will pay for that claim. In most cases, they pay us directly, so you don't have to wait for reimbursements and you only pay the difference.  If you don't have pet insurance yet and and are interested, you have the option to get a 30 day free trial of Trupanion Pet Insurance at your pet's next exam.  If you have any questions or are coming in for a visit, do not hesitate to ask us about this great new service.  You may also visit for more information.

You asked and we listened!  OSSVH is happy to announce that we are now accepting American Express as a form of payment. We know that many of you have been asking for this option for some time now and we are excited to be able to provide more flexibility in payment options to our clients.
