My husky did a similar thing and ate a block of the pinkish mouse poison in my shop. I brought her to the vet in Hagersville. They gave me a large syringe that I was to fill with hydrogen peroxide and squirt down her throat. It didn't take long until she threw it all up. We did it a second and third time to be safe, as per the doctors orders, and she has been fine ever since. Cost:$4.
