North Yorkshire Police is appealing for information after two pet dogs were poisoned in Pateley Bridge with the same combination of poisons used to kill local birds of prey.

The two dogs fell seriously ill while being walked in April. One did not survive.

Samples from the dog that died found four poisons, which combined together have been named locally as a Nidderdale cocktail.

The tests concluded that exposure to the poisons was the most likely cause of the dog’s death.

The Stray Ferret has previously reported an increase in bird poisonings in the Nidderdale area after six birds died due to suspected poisonings.

To encourage people to come forward with information, local businessman Keith Tordoff has offered a £5000 reward.

Police are appealing for information about animals being poisoned in the area.

Inspector Matt Hagen, head of North Yorkshire’s rural taskforce, said:

“The fact we have seen this same combination of chemicals, the Nidderdale cocktail as it is sometimes known, also cause the death of birds of prey in this same location would indicate that the poisons have been deliberately left in a place where they could be found by wildlife and unfortunately in this case, domestic pets.

“Pesticide abuse of any kind will not be tolerated and we are doing everything we can to try and find those responsible.”

The test results and local intelligence led North Yorkshire Police to search several properties in the area. However, none provided any clear evidence about how the poisons reached the two dogs.

The poisons are chloralose, bendiocarb, isofenphos and carbofuran. Chloralose is licensed for use in England in low concentrations but the other three are all banned.

Police have warned that none of these chemicals should be used in an environment where domestic animals or wildlife could come into contact with them. A person misusing pesticides could be charged with a variety of offences.

Mark Thomas, head of investigations at the RSPB, said:

“Carbofuran is one of the most commonly abused substances in the poisoning of birds of prey. It is a highly toxic, banned substance putting wildlife, pets and people at risk.

“This is not the first time harmful substances have been found left out in the open and sadly it unlikely to be the last. This reckless and irresponsible behaviour, which had led to the death of a beloved family pet, cannot be allowed to continue.”
