I just got mine today and Bella (shih tzu) LOVESSSS it!! she has not put it down!! They do stink though

I got them from bestbullystick.com! Next time I will have to try to oder free ones
Does anyone know if 13 weeks is to young to give a bully stick to? Gabby wants to try Bellas so bad but I wont let her because I do not want it to hurt her!!
