Carcasses dumped alongside the Waiohine River have incensed a Greytown dog owner who says the rotting remains threaten the health of her pets.
Vicki Rennie daily walks her pair of labradors, Max and Zoe, along a newly-laid walkway that joins a lead-free route alongside the river.
She had beenlanded with weighty vet bills in February, she said, after her animals feasted on the remains of a butchered deer they discovered on the riverbank route.
"Then last week we came across another deer carcass - well, the head, hooves and other bits at least - all stuffed into supermarket bags. It was disgusting and I'm scared my dogs will get sick again, or worse, if the dumping continues.
Ms Rennie said she was appalled to discover a festering pile of lambs tails dumped along the same route while walking her dogs on Wednesday.
"There's all sorts of rubbish dumped along there and it's one of the only lead-free areas that's easily accessible for so many dog owners in Greytown.
"There's old stereos, green waste, undersized paua shells, all sorts, dumped along the riverbank. It's just so infuriating that a few people can threaten the health of our dogs and taint what is an asset for us all.
"It's a health hazard, absolutely unsightly and unpleasant, and criminal."
