How funny, Toby and Lucky's breeder says the same thing! She says males are more affectionate, too! I have only had males, so I have no experience. I think it has to depend on each dog's individual personality to some extent though. When a breeder says that, they have had many, many dogs come and go and overall maybe males tend to be the more affectionate sex, but certainly that doesn't mean the females aren't affectionate! I think it's like the tendency for females to be more obedient, while it certainly isn't always true, most dog trainers I have ever met say there is definitely some truth to it in a big picture sense. I want my next beagle to be female! With a husband, two sons, and two male beagles I could use a little female personality in the house!!!
