The earliest veterinary association attached to the PVMA is the Cebu Veterinary Medical Society which was founded in 1963 November. This was headed by Dr. Nestor R. Alonzo, UP-CVS 1937, president and Dr. Rosalio C. Mandin, UP-CVS 1937 as his vice president. Dr. Rodolfo C. Orais, UP-CVM 1963, Dr. Juan C. Vertulfo, UP-CVM 1958 and Dr. Jose L. Guadiz, UP-CVM 1960 were secretary, treasurer and auditor respectively. It was short lived and was only listed in the 1964 PVMA Souvenir Program. It is noteworthy to say that Dr. Nestor R. Alonzo remains unrecognized by the PVMA as an outstanding veterinarian whose activities had national implications.
The earlier PVMA constitutions did not provide for chapters; however the 1982 constitution, Article IX, entitled Chapters, codified the formation of chapters. While rules in forming a chapter were drafted, there was no continuity in its implementation. There appeared to be a confusion in the formation of a chapter and the use of terms in naming the chapters. The nomenclature to be used should be geographical in nature with the word PVMA as a point of reference. Guidelines for affiliation was issued in the 65th Annual PVMA Convention held in 1998 February 19; Dr. Daniel C. Ventura, Jr. headed the committee on affiliates and chapters. In 1999 the PVMA board through Dr. Edna Zenaida A. Velarde-Villacorte presented the issue to the House of Delegates on November 12 for review. This was later approved by the PVMA Board for adoption. This was recently updated by the PVMA Board in 2006 October 28 in a morning meeting. This was presented to the House of Delegates in the afternoon.
Veterinary Associations who are not Chapters relate with the PVMA through affiliation. These are independent veterinary organizations whose objectives are congruent with the PVMA. These affiliates however, do not compete but compliment the function of the PVMA. They accept the fact that the PVMA is the lead veterinary organization in the Philippines.
Since 1974 many veterinary associations have officially affiliated with the PVMA. The veterinary associations in the 1970’s and the 1980’s are the City Veterinarians League, the Veterinary Practitioners Association of the Philippines, VPAP, the Veterinary Women's League, VWL, the Philippine Animal Hospital Association, PAHA, and the Philippine Society of Veterinary Diagnosticians, PSVD. The VPAP and the VWL affiliated with the PVMA during the Business Meeting in the 42nd Annual Convention in 1974 December 14. The Veterinary Women’s League, The City Veterinarians League in the Philippines, and the Philippine Society of Veterinary Diagnostician are currently not active.
