Stray Pitt in yard

Today when the two dogs were outside in the yard, we heard a commotion going on and opened the side door to see a very large Pitt Bull in our yard, he might have been a stray , he had no collar on and looked kinda dirty but large and and well fed.
All the dogs came running when we called them and my boyfriend locked the Pitt in the yard, and Rita and Face were both acting strange she would not let us near her and had her tail between her legs, i started to think he raped her, but she is fine now, so anyway we looked out the window and he was climbing the fence to the Great Danes yard behind us, i got in my car and searched all the streets for him with treats to lure him with, but i could not find him.
I think he has been here b4 because the dogs have been going nuts the last few nights i let them out.
Anyway i was just sad that i could not help him, and worried in case he returns and gets in a fight with my two, i have to keep a extra eye on them now, :(

aww thats sad:( I hope he comes back so you can feed him,and mabye give him to a Shelter or find the owner.

Oh poor thing! That's just how the poor pit's end up in trouble when the owner lets them run. I hope he makes it home or if you see him again that you can catch him. It's amazing how the pit's can climb. I sure hope everything will be ok with him and your two.

dont feel bad,, you tried,, thats what counts...

I wish he had a collar/id.
That is so sad, obvious he is well fed and
someone must be missing him.
