(1) Background: As part of the ongoing endeavor to eliminate dog-mediated human rabies in Thailand, renewed interest has been shown in oral vaccination of dogs as a supplementary tool to increase vaccination coverage of the dog population.(2) Methods: Three different bait types were tested using a hand-out model on the campus of the Kasetsart University and the surrounding temples in Thailand during September 2017, consisting of two industrial manufactured baits (fish meal and egg-flavored) and one bait made from local material (boiled pig intestine placed in collagen casing).A PVC-capsule containing dyed water was dc wire harness inserted in the bait.(3) Results: The fishmeal bait was significantly less often accepted and consumed (50.29%) than the other two baits (intestine bait—79.

19%; egg bait—78.77%).Delivery and release of the dyed water in the oral cavity was highest in the egg-flavored bait (84.50%), followed by the intestine bait SORE THROAT SPRAY (76.61%) and fishmeal (54.

85%) baits.Bait acceptance was influenced by sex, age, and body size of the dog.Also, the origin of the dogs had a significant effect: temple dogs accepted the baits more often than street dogs.(4) Conclusion: A significant portion of the free-roaming dog population in this study can be vaccinated by offering vaccine baits.
