Additionally, your pet can develop a resistance to the drugs if they keep taking them. On the bright side, we collated a lot of natural antibiotics for dogs you can use for your pooch with little or no side effects.

Consult your vet

You need to tell your vet about your plans before executing them on your dog. Though herbs are natural, they can be harmful if used wrongly. Your dog’s underlying health condition, allergies, and body system make all the difference.
