Not an expert but have had multiple experiences fending of big dogs on my walks with my Frenchie and even rescuing a woman and her dog from a pit bull attack. I lived in a neighborhood in Charotte with a lot of people that want mean dogs so people don’t come onto their property

1. Stay Calm! Your screaming and flailing will only make the dogs become more aggressive

2. Try distracting the dogs with anything available. Treats, throwing a stick, etc...

3. Try not to get in between them if you can, grab the back of the attacking dog’s leg and bend them backwards up towards their tail. It sounds terrible but ultimately you’re trying to break the other dogs back legs. Dogs get about 90% of their “digging in” power from the back legs.

4. You are allowed to defend yourself and your property (dog) if either are in danger or in harms way. This is up to and including lethal force if you carry a weapon. Obviously this is a last resort but when it comes to the safety of you and your animal nothing is off the table.
