Mastiff breeds are best guard dogs for home.
Mixed breeds can be trained to do anything that purebreds can do.
There are many breeds of dogs that are used for agility including the grey hound. This is because these dogs have long slender bodies that have great flexibility.
While a variety of breeds may be used to hunt forensic material, bloodhounds, springer spanels, and labradors are the most common breeds used as cadaver dogs.
Police work, army and guard dogs
They were bred to be guard dogs.
Many dogs are used, but the most common is the pit bull.
Drug dogs in other words dogs used to sniff out drugs can be many breeds of dog. Drug dogs are often dogs with very good sense of smell. Most commonly a German Shepard, however, many other breeds can participate in "drug sniffing". For example Bloodhounds or Labs are sometimes used in airports. Also Bloodhounds can be used on a paralegal case simply because these dogs can sniff out trails hours after they were left. There are also breeds of dogs which can sniff out mold in walls and such. I hope this answer helps it's viewers!

German Shepherds are a fantastic breed to have for protection, and they do quite well with other German Shepherds and different breeds as well. Most breeds of dogs can get along, the key is training. Poor training will produce poorly behaved dogs that do not get along and can be aggressive. Firm training will produce highly trained and sound of mind animals. I recommend German Shepherds, as an owner of 2, and a Mom of 2 little ones, I see how protective yet loving additions to the family they can make.
Yes. They have even been known to be service dogs to CHILDREN.
