Graphic images of six burned dogs have caused outrage on social media.
The animal rights organisation Pata de Perro (Dog’s Paw) published the disturbing pictures online.
The burned animals had been found by a neighbour in the colony Altares II, located in the city of Hermosillo, in the north-western Mexican state of Sonora.
They reported the incident to police, who are investigating the case.
The organisation asked authorities to punish those who burned the dogs as it was a cruel act and according to Carolina Araiza, coordinator of Pata de Perro, those who are responsible of this type of cruelty to animals "end up committing crimes against people".
The pictures of the burned dogs were posted with a message saying that the government of Hermosillo will investigate the case and asked netizens to report similar cases.
The pictures caused outrage among netizens, such as ‘Tony Mendez’ who wrote: "This is a very serious problem! The government should find a solution [to the problem of stray dogs] and the way is not to kill them, but maybe sterilise the dogs."
Netizen ‘Chary Fonllem’ added: "Actually when I see these kinds of things I only want to apologise for human cruelty. I do not want animals to feel that all human beings are like this."
In December 2015, the state of Sonora approved some reforms to the current animal protection law to make animal abuse a serious crime.
Article 342 of the Penal Code in Sonora says that those who commit this type of crimes could face between six months and two years in prison and a fine.
