Lost/Abandoned dog.

It's happened again.
A very friendly,happy and partly trained dog has turned up on our doorstep.She has a Scalabor collar,she sits and gives a paw on command and is great with other dogs.She is a golden lab cross ish with what I don't know.
She is medium size and,we think,about 6 mth's old.She would make a wonderful family pet.We can't take her on.If nobody claims her,or homes her,her future will not be good.We have re-homed/rescued half a dozen now and we have run out of friends who have a dog so if there is anybody looking for a well behaved and friendly young dog get back to me.
