But I have said nothing about the subject. To make a sentence I must say something about the girl. If I say The girl dances well, I have expressed a complete thought and I have made a sentence. In grammar the person or thing we speak about is called the subject. What we say about the subject is called the predicate.
The Belgian Laekenois is a medium sized dog that weighs between 50 and 65 pounds. The rarest of the four Belgian Shepherd dogs, the Belgian Laekenois is a sturdy, well-proportioned medium-sized dog with a rough wire coat that easily distinguishes it.
Remember not all dogs grow at the same rate, so you can't always go by a growth chart for puppies. Some puppies are slow growers, whereas others may have early growth spurts and slow their growth as they age. Most medium sized dogs, Golden Retrievers included, actually reach full growth by 12-18 months, not two years.
