There are times when the health issue of your pet is so severe that you must use an antibiotic drug. But there are side effects to them:
Immune-mediated anemia and platelet problems
Immune-mediated joint inflammation
Some of these side effect will subside or can be diminished by taking the antibiotics with food, and taking probiotics during the course of the antibiotic treatment.
For illnesses that are not acute, try taking any of the following herbal antibiotic substitutes:
Echinacea (not for long time use)
Licorice (not for long time use)
St. John's Wort
For skin problems requiring topical antibiotics, try:
Herbal rinses with chamomile and goldenseal
Dosages: I use the rule of thumb my vet told me --- to give 1/8 or 1/4 of what a human dose is, depending on the size of your pet.
I am not a vet and have no medical training. Please take your pet to a vet for any serious injuries and conditions. And it goes without saying...always talk with your vet before giving herbs if your animal takes other medications. Herbs can react with other drugs.
