Direct Stop Animal Deterrent Spray was developed specifically for Use in controlling aggressive animals.
It is safe for humans and pets, while providing a strong deterrent for the animal. The Direct Stop formula contains a citronella grass. The propellant used in Direct Stop is safe for humans, animals and the environment (ozone friendly).
How Direct Stop Works: The strong force of the spray combined with the Citronella odour distracts the animal from the object of its aggression providing valuable additional seconds to help enable the user to retreat to a safe place.
This method of distracting the animal avoids the potential of bringing out more aggression, as may be the case with some animals that have been sprayed with pepper spray.
CAUTION:
Although Direct Stop has been shown to be as effective as 10% Pepper Spray in dogs, it may not stop trained attack animals or those with a strong motivation to attack.
Our dog trainer always carries this spray when in class or out with her own dogs.
I doubt these dogs will jump the fence to attack, these sorts of attacks are rare but do happen. If you enter its territory an attack is very likely, but for a dog to jump a fence to attack you they have to be very aggressive. In all likelyhood they are just bored, and / or scared. If you are really worried about the dogs, report them to the authorities - you have the right to walk down the street without being intimidated by someone's dogs.
Don't eyeball the dogs - direct eye contact is dog body language for a challenge and / or downright aggressive. I wouldn't try and feed them - walking up to them even with food could upset them. Just walk on by on the other side of the road and leave them well alone.
If they do jump the fence to attack you, the bad news is that in all probability they are highly motivated to cause you damage. The spray / stick might well not be enough, but use them. Don't run. Blow your whistle to try and attract attention and help. Aside from that I'm not qualified to give further advise - I will ask our dog trainer next time I see her
