The Leonberger dog looks like a lion. Coming from Leonberg, Germany, this large breed may look bigger than he really is. Although this breed has a very thick coat, he still tops the charts at 115-170lbs.
This breed has a personality as large as its body. The Sarplaninac has a fantastic temperament and is an excellent working dog. Highly territorial, the dog is suspicious of strangers. This attitude makes the Serbian Mountain dog an exceptional guard dog.
