The Provincial Veterinary Office of Marinduque was created by virtue of Sangguniang Panlalawigan Resolution No. 092  Series of 1994, separating the said office from the umbrella organization of the Provincial Agriculturist.  Its legal basis was excerpted from Article 19 of Republic Act 7160, otherwise known as the “Local Government Code of 1991”,  where Section 489 of said Act  stipulated the mandatory appointment of a Provincial Veterinarian, and mandated the office to take charge the day to day operation of the Provincial Veterinary Office, and shall be responsible for the effective delivery of basic veterinary services with separate administrative appropriation from that of the Provincial Agriculture Office making the two offices co-equal and distinct from each other.

The office leads the front-line of veterinary related activities, such as in the outbreak of highly-contagious and deadly animal diseases with economic and public health importance and in situations resulting in the depletion of animals for work and human consumption, particularly those arising from and in the aftermath of man-made and natural calamities. likewise, the office was mandated to enforce all laws and regulations for the prevention of cruelty to animals,  tasked to institute measures to eradicate, prevent or cure all forms of animal diseases and to regulate the keeping of domestic animals.
