ok guys i just picked up a 12 acer horse farm to mow, there are only 3 acers of grass anyway thats besides the point. the home own has 2 pit bulls that have free run of the place, the owner warrend me that she had them but assured me that they are "friendly" and would leave me alone. as i was mowing i noticed the dogs walking around but they never bothered me and any time i got close to them they started wagging there tails and what not. and when i stoped to move a trampoleen the one came up and was giveing me kisses and being very friendly. my question is do i have to worry about these dogs? i here alot of storys about bit bulls attacking and how they can be friendly one sec and ready to attack the next. what do you guys think i should do? thanks alex ps. don't mind my spelling i'm t olazzy to do spell check after mowing all day.
