This is a component of the Veterinary Teaching Hospital. In the UPLB campus, the resident veterinarians are mainly members of the Department of Veterinary Paraclinical Sciences. Various specimens like blood, urine, feces, etc. from clinical cases at the hospital and sick or dead birds and livestock brought in from the field are examined by clinical students under the supervision of faculty members. In addition, various diagnostic laboratory procedures such as bacterial isolation, sensitivity testing, virus isolation, HI test and other serological procedures are conducted in this laboratory. The ADDL is mainly housed in the Tabon Facilities, near IRRI. It also maintains a section in the Veterinary Teaching Hospital building at the UP Diliman Campus.

In order to give veterinary students more exposure to field cases in the rural areas, clinicians who are on rotation at the Food Animal Clinic (FAC) regularly go to towns and barrios in different provinces where extensive programs on animal production and animal disease control like anti-rabies vaccination are undertaken. Students also attend to sick calls from different farms in the nearby surrounding areas.

Aside from the facilities of the College, those of the Bureau of Animal Industry, International Training Center on Pig Husbandry, Philippine Genetics, Inc., National Stud Farm, Veterinary Inspections Board, Manila Zoological and Botanical Garden, National Meat Inspection Commission, as well as private veterinary clinics, abattoirs, food processing plants, and commercial farms are utilized for instruction.
