Several people in my local area have taken to scattering bird seed that contains raisins/sultanas on the ground or on little food stations that are low to the ground. A friend of mine had to take her dog to the vet this morning because he was snaffling around and started tucking in before she realised it was raisins.
Raisins (even in very small amounts) are toxic to dogs, cats and possibly other wildlife like foxes.
I've posted on the FB group for my local area as well but just wanted to put it on here to share as widely as I can!
