Once they had gathered there was no hesitation in sharing the news with them, fortunately getting straight to the point. Though they were all rather patient children, the curiosity surely would have gotten to the better of them and one would have asked what was happening.

More siblings? He didn't quite understand how all of that worked just yet though of course understood the concept that somewhere down the line this news meant there would be more pups in Threar. Someone with jealous tendencies may have felt the family still certainly big enough though such a thought didn't enter the sweet boy's mind. He was still very much speechless however, certainly not having expected that news at all and so he would simply match his father's silence for a moment. Hopefully it was clear enough that he wasn't horrified by the news, simply surprised.
