How hard do dogs cum while tied?

I mean what they feel rather than just the fluid volume. Of course they can't directly tell us, but perhaps their body language gives clues? Is it constant spasming heaven during the whole tie? Or more intense before the turnaround? Or several peak orgasms during a long calmer pulsing?

Bumping this old post. I really love when people try to imagine and describe what an animal feels in their throes of passion, but unfortunately that's quite uncommon. Would anyone who's been intimate with a dog like to share their thoughts?
