Chicken breasts laced with pills have been found in a Northampton garden, pet owners are being warned.
The RSPCA is investigating reports of poisoned meat being thrown over a fence in the Wellingborough Road area.
The meat could be used to poison dogs, cats and other wildlife.
It is unclear what the tablets are and what harm they do.
But Darren Knagg, landlord of the Fiddler's pub, in Wellingborough Road, found some of the meat on his property.
He said: "We've had meat thrown onto the property. This has happened twice now over the past two days.
"I stepped out for a beer delivery in the early morning and found this meat stuffed with yellow pills hanging from part of my fence.
"I've got two dogs on site. I'm worried whoever is doing it might be trying to poison them so they can break in."
Anyone who finds any meat in their garden is being asked to bring it into their nearest veterinary surgery, who can then send it away for analysis.
If you are worried your pet may have eaten any poisoned meat, official advice is to contact your vet immediately.
