Female, female, male, whimpers or female submissive, maybe sore howls, nothing happens run PUP DISTRESSfor a long time. Mix it up. Get a response and move on them if they don't come. There are no rules. I'm only doing 3 minute breaks on howls and maybe 3 or 4 howls at a time. pup distress can go for 10min switching back and forth with various pup/canine/and mouth calling. Just something that has worked for me recently.
