He's trolling him. He never slept with the dog, his brother is just being an ass to try to force Chase to act more like the alpha he thinks he should be.
Actually he only wants him to release pheromones, because they all know of the consequences if they don't do it, since their father is affected by it for the rest of his life. Grayson misguided way of helping, his methodes, are one problem, the other is that the author seems to like to see Chase suffer and made him an idiot, since he could avoid dealing with Grayson if he uses his brain.
i mean is quite telling that this man is LYING and just pushing Chase but the police still needs to handcuffed his brothers
what the actual fuck, his brothers are fucking sick someone call 911 buddy literally just admitted to r a p e and using it with a dog
