It is extremely dangerous to administer any medication to your dog without consulting a veterinarian.
Here's why:
* Dosage is critical: The correct dosage of penicillin for a dog depends on factors such as their weight, age, and the specific condition being treated. Giving the wrong amount can be harmful or even fatal.
* Penicillin can cause side effects: Dogs can experience allergic reactions to penicillin, and some may have other complications. A veterinarian can monitor for these and adjust treatment if necessary.
* Underlying conditions: Your dog may have other health conditions that make penicillin unsuitable or require a different dosage.
Please contact your veterinarian immediately if your dog needs medication. They can provide the correct dosage and instructions.
