I need to find homes for these two puppies

One boy (red collar) and one girl, both from the same litter. They were from a litter of strays, so we don’t know the breed. We think it’s some sort of pit mix but we aren’t sure. I have to get rid of these. I cannot keep them, I can’t have any more animals. They are only about three months old, and are already being kennel trained. Please help.
