The state of Massachusetts has released a list of dates and locations for its 2010 rabies vaccination clinics. These scheduled clinics allow dog and cat owners to affordably update their pets’ rabies shots, which are required annually by the state.
The list can be found online here: http://www.mass.gov/agr/animalhealth/rabies/vaccinationclinics.htm.
To safely transport your pet to the clinic, make sure cats are placed in solid (not cardboard or soft-shell) carriers. Dogs must be at least on a leash. All pets must be held by a person who is over 18 years old.
