We just learned about the type of dog the Pomeranian
Another type of dog is the rottweiler.
This type of dog has been around for a long time, and was used to herd livestock, pull carts, and be a guard dog.
Now they are used as search and rescue dogs, guide dogs for blind people, guard dogs and police dogs.
Rottweiler's are always black with brown feet, a brown belly, brown mouth, and little brown dots on their eyebrows.
