The vet may treat your dog through the use of activated charcoal and/or other methods that work to remove the toxin from the dog’s system. Some dogs may also require IV fluids, supplemental oxygen, and other medications to treat symptoms that may arise.
Dogs who have a mild case of motor oil poisoning usually make a full recovery, especially if they receive medical treatment as soon as possible.
