In Nizamuddin East in India there were 18 stray dogs found poisoned:

Local dog lovers have filed a police complaint, alleging the animals, most of whom were vaccinated and fed regularly by the residents, were deliberately poisoned.…

Sumita Mehta, another resident, said, “I have been repeatedly asked to stop feeding the dogs. I feel the colony is safer when there are dogs to guard us. Due to their presence, no monkeys come to the area anymore to bother us.”

In Taranaki, New Zealand, a couple of dogs have suffered the ill-effects of a poisonous plant. Sally, a Bichon Frise died after eating the shrub:

Poisoning was dose-related, meaning it was only lethal if dogs ate a lot of the plant.

“If they only eat a little we can pump their stomachs and give them a sedative, but in Sally’s case it was just too much.”

The yesterday, today, tomorrow plant – brunfelsia latifloria – is a fast-growing decorative shrub popular for its leaves which fade in colour from purple to white in the days after it blooms. It is particularly common with people doing ‘garden makeovers’.

The plant’s principle toxin is brunfelsamidine, a neurotoxin.
