You want to reinforce behavior you like, such as when your dog looks at but does not react to another dog a good distance away. If you have to stop an incoming assault from an off-leash dog, you can yell “SIT!” at the oncoming dog (sometimes it works) and then throw your meat treat on the ground near that dog and do a quick, calm U-turn and move away. Could the dog have some sort of meat allergy? Possibly. That’s just one more reason the dog’s owner should obey the leash laws.
Throw a meat treat in the direction of the oncoming dog, turn on your heels, and walk away. I cannot even count the number of dog owners who are shocked that as their dog is being harassed by the off-leash dog, the owner of stands there, saying nothing, and doesn’t help to put an end to the situation. If another person is walking with you, ask them to attempt to catch the oncoming dog as you leave the scene (you have to decide in an instant if that would be a safe maneuver or not because breaking up a dog fight is an excellent way to get bitten).
In Connecticut, dogs are not permitted to run at large except in the situation of hunting. Still, if the dog has vicious propensities and the owner still allows it to run at large and a person is bitten, the owner can be fined for up to $1,000 and is also liable for 6 months of prison unless the victim has abused the dog and provoked the harmful behavior.
