I think they happened at different times, but you're right.

Chase can’t remember about doing it with joshua. So when he knows he also blames himself for graped joshua and thinks about the dog (but ofc that doesn’t actually happen his brother just lied about that)
Ohh, I knew it. Thank goodness.
My patience is running thin, and I need to see how Chase finds out that he is Pete's father. However, based on my own observation, Chase was not actually involved with a dog. I believe that happened when he was in a rut, and Joshua happened to be there, which is why Joshua became pregnant with Pete. Please correct me if I'm wrong.
