Police in Thailand rescued more than 1,000 of the animals from tiny cages when they intercepted four trucks attempting to smuggle them out of the country.
The dogs -stacked high in scores of crates - were being transported to Vietnam as officers swooped in two raids in Nathom and Si Songkhram districts near the border with Laos.
Livestock officials in Nakhon Phanom confirmed 1,011 dogs were being looked after at a government shelter.
Another 119 died from suffocation in the cramped cages or when they were thrown into the trucks as the fleeing traffickers tried to speed away.
Two Thai men and a Vietnamese man have been charged with trafficking and the illegal transportation of animals.
If convicted the accused face a maximum one-year jail sentence and a fine of up to 20,000 baht ($670)
The dogs were to be taken across the Mekong river in Laos. Prices for stray dogs and pets in rural Thai villages can reach as much as $33 an animal. Read More
