Activated charcoal capsules can also be given orally for poisonings - the charcoal absorbs many poisons. The capsules are neater to use than the powder, and can be administered fairly easily. One capsule is usually sufficient for a cat or small dog and two for larger dogs. These disinfectants and bandages can be founds at any pharmacy. There are also some homeopathic remedies that are good to have on hand, which can be purchased at natural food stores or through natural pet catalogs or holistic veterinarians.
Remedies come in different potencies, or strengths.
I usually use 30C potencies, which are normally quite safe and produce no side effects. Give the pellets orally, under the tongue. Do not give them with food. If you have some water, you can dilute the remedies in water and administer them that way. In addition to small pellets, many remedies also come in ointments and gels.
