Forty one severely malnourished and emaciated dogs were rescued from a farm in Spain.
The animals were being kept in 'terrible' conditions with the woman who lived there arrested and accused of animal abuse.
Officers were alerted to the farm, near Quintanar de la Orden in the central province of Toledo, by a local animal charity and arrived to find dozens of starving and dehydrated dogs in the 'unhygienic' building.
A woman who lived at the farm with her partner and was responsible for caring for the dogs has since been arrested.
Police say it is not yet clear why she was keeping such a large number of dogs.
The animals had not been microchipped and also did not have legally-required paperwork on their health.
Officers say 29 of the dogs were so weak that they could not eat and had to be fed via IV drip, but all are now recovering.
The animals are being housed with local charities until they can be rehomed.
Police said in a statement: "Thanks to information given to us, it was possible to save the lives of 41 dogs who displayed serious symptoms of malnutrition, organic deterioration, physical weakening and dehydration.
"It is not clear why she had so many dogs which she kept in such terrible conditions."
