Dogs - Size does matter
The ethical way to breed dogs
Are you keeping your dog active enough?
Dogs - Are males better than females?
Don't ever think that female dogs have the menopause, so unlike the human female, dogs can have puppies practically all their lives. Guarding your female dog is an activity that you are expected to do for a great deal of time in every year because male dogs either from your neighbor or those stray ones can catch her scent no matter how far they are. If you want to breed your dog, then you might as well go for a female pedigree dog since it can really give you a lot of advantage in terms of a financial aspect.
