Final answer:
The treatment for brodifacoum poisoning in dogs is to administer Vitamin K1 for 6 weeks and monitor the dog's serum calcium levels.

To treat this dog, you should recommend treating the dog with Vitamin K1 for 6 weeks. Vitamin K1 is the antidote for brodifacoum poisoning, as it helps restore the blood's ability to clot. Additionally, it is important to monitor the dog's serum calcium levels today and once weekly for 6 weeks to ensure there are no further complications.
