Bablefish gives the following translation. I've done a bit of editing for clarity. I thnk "el canil" means dog park, and have translated it as such.
The Center of Adoption of Mascots alerted in the last hours that food for dogs with nails in their interior was found within the dog park of Centennial Park, in the City of Buenos Aires. " Minutes ago I returned from taking a walk with my dogs at Centennial Park. As always we went to the canil and on the ground were small pieces of ham and a piece of blood sausage tirados," the person who found the food posted on their Facebook page. No one paid them much attention, until we accidentally stepped on one and we saw that inside it had a nail. When we began to look at all the pieces of food that had been thrown on the ground, they were all the same. We picked them up and threw them away. The small pieces of food were scattered all over the dog park, and they all had nails inside with sharp points. The Center recommended to alert the dog owners of this fact.
