I WAS THINKING THE SAME THING OMFG
I made a comment clarifying this. It wasn’t josh either. He didnt fuck anyone until he met josh years later as an adult

It was with josh, but grayson lied that chase did it with the dog that's why he has ptsd. And also because its his first time sleeping with someone (josh took his virginity)
Yall just clarifying: that night he didnt fuck the dog NOR JOSHUA. What happened was chase refused to release his pheromones or have sex which lead to him having a rut, his brother did bring the dog with that purpose but chase passed out before anything happened. He was a teenager at the time. After that, because he couldnt remember, his brother used this event as a way to blackmail him into going to those sex parties. Still he would fuck no one, they would only take him and he would pass out and they would remove his built up pheromones manually. What happened with josh was a different situation. It was actually his first time. So at the end of the day he has only ever been with one person in bed which is josh, which is why he is so inexperienced compared to josh.
I read the novel so this is legit information btw. Hope it clarifies some things
Funfact: chase is also 5 years younger than joshua, i absolutely adore their dynamic
What if it wasn't the dog but it was actually Joshua. Didn't Joshua say he didn't used to be afraid of dogs. Maybe he didnt know that it was actually an omega that he slept with aka josh. So guys dont be to worried about the dog situation. Totally different note his brother fucking sucks and he needs help or death.
