What dose of activated charcoal is used in dogs?
Vet at FirstVet answers:
Often you give 1-5g of activated charcoal per kg body weight. Activated charcoal is used for certain types of poisonings. You should contact a veterinarian before you administer activated charcoal to your dog, since it is not recommended in all types of poisonings/toxicities.
