Pre-exposure anti rabies vaccinations will protect you, and apart from that, you can also make sure you avoid direct contact with dog saliva. Try to always have some help with you to avoid unexpected scrach or bite when you concentrate on feeding them

For personal safety wear gloves and avoid coming in contact with saliva by not feeding directly and avoid any licking. Get one dose of anti rabies vaccination once a year and get post bite vaccination in case of any bite. For scratches try wearing full sleeves generally these scratches are harmless but avoiding then is best for in long term

If you have completed the full course of the anti-rabies vaccine and are feeding stray dogs, you are better protected but should still take precautions to avoid potential risks of exposure to rabies or other infections. Here are the precautions to follow: 1. Avoid Direct Contact with Saliva or Blood: Ensure you do not let the dogs lick your hands or face. Use utensils or disposable plates to feed them instead of your hands. 2. Wear Protective Clothing: Wear gloves and long-sleeved clothes to avoid scratches or bites. If gloves are unavailable, wash your hands thoroughly after feeding. 3. Stay Calm and Observant: Avoid sudden movements or loud noises that may agitate the dogs. Observe their behavior for any signs of aggression or unusual activity, which could indicate illness. 4. Feed in an Open Area: Choose a spacious area where the dogs can eat comfortably without feeling threatened or crowded. 5. Avoid Feeding Sick-Looking Dogs: If a dog appears sick, excessively drools, or behaves aggressively, maintain a safe distance. Report such cases to local animal control or veterinary authorities. 6. Wash Hands Afterward: Wash your hands thoroughly with soap and water after feeding or handling dogs, even if you wore gloves. 7. Stay Updated on Vaccinations: Ensure your rabies booster shots are up to date as per medical advice. Keep a record of your vaccination dates. 8. Educate Yourself About Rabies Signs: Familiarize yourself with the signs of rabies in animals, such as unprovoked aggression, excessive salivation, or disorientation. 9. Carry First Aid Supplies: Keep basic first aid supplies like antiseptic solutions and bandages in case of minor scratches or injuries. 10. Inform Others About Safety Practices: If others are helping you feed the dogs, educate them on safe practices and the importance of avoiding close contact with stray animals. By following these precautions, you can continue feeding stray dogs while minimizing health risks.

Since you already had a three-dose rabies vaccination six months ago, your body has developed immunity. Superficial scratches without blood or puncture wounds do not require post-exposure rabies shot. But still see your family physician in this regard.
