| I found this on an Australian Shepherd site.
The male Australian Shepherd will usually stand 20-23 inches and will weigh around 50-65 pounds. As with most animal species, the male Aussie is the showier of the two sexes, carrying longer hair, heavier bone, and a more masculine head. He typically has a very regal air about him. Males do have a tendency to be territorial and do not always take well to having to share their space with other male canines. Again, if you are not planning on using your male for stud, you should think about having him neutered to make life easier for all parties concerned.
Now after that is said, our brother in law had two males purebred, six years apart, both neutered. Never once was there a problem, it think that is not the norm.
Hopefully your dad will be lucky. |
