I was going to go with some sort of spaniel mix. (paps are spaniels actually)
This will sound weird but her feet especially look spaniel, imo. Most spaniels have hare feet that are very long like hers.
there's also something almost JRT about her, imo. So I'd guess some sort of smaller spaniel (not sure what kind) x JRT. Or just to be general a spaniel x terrier.
