Hello, and thanks for using Petco Pet Education Center, formerly Petcoach. There is no known toxic dose of Vitamin B12 in dogs, and no toxicity cases have been reported. Zorro should be fine! However, if those pills contain anything else (including the sweeter Xylitol) then please reach out again, or consult with your veterinarian. Hope this helps!
