Thanks for the replies. His pricked ear is what I was hoping the other would do, as we have owned a SBT before and his ears were similar to this.
I haven't yet contacted the breeder, but I will tomorrow. We are not planning on showing him, he is just a very much loved family pet.
I guess we are just very observant to everything at the moment as he is only new to us and his floppy ear was bothering me.
