Unloved dave

Dave was left unwanted on a farm I work at last september by some guy and the farm lady brought him down to me to rehome... -_-; ...unfortunaly with animals I can't say no if its in a situation where they are going to be put down if not taken in, So It wasn't really a choise. :/
He has been very unsucessful in finding a home. Found him one with a older lady that just wanted a dog for company and there was ment to be no children but got a phone call 2 hours after her trail period ((I always give people a week to see how they get on)) And she said he bit a child, so ovbiously went up to pick him up and see what was going on and she and the mums in the neighbourhood locked him in a room with 13-15 young children on their own while they were upstairs having coffee. ...So I was proud of myself for not swearing but i did give every mother there a hell of a lecture. and the woman tryed denying I said he wasn't good with children but i get people to sign paperwork before trialing a dog with conditions of having it after making them read it so no trying to pull the wool over anyones eyes there...was very annoyed that day.
I would have trusted him around visiting children whilst supervised, and he's create trained. But only people with young familys try getting in contact with me about him so obviously that wont work out and I wouldn't put Dave or the children(even if i don't like them. xD ) at any risk.

He's looking for a older person who lives on their own with no children.
He's very loving and loves to play with his ball.
He's a Male, Pug x jack russell, about 3 years old.

He's on many rescues in my area homing list but as of far no luck. :/
(Plus Loki doesn't really like little jack russell things so dave's crated most of the time while I'm out. <.<; ).
Going to try 2nd chance animal rescue again if i don't hear back from them by wednesday, they are ment to be quite good at homing small dogs... heres hoping. xD
