According to the text how are Search-and-Rescue dogs and Detection dogs different?

Dog or Wolf?

Wolves and dogs share a common ancestor – the wolf. Over time, dogs evolved and changed while wolves stayed the same.

Dogs and wolves are very different species now, however, they still share many similarities.

Brains

Wolves and dogs are both very smart. You can teach a dog how to do many tricks and dogs quickly learn their names. Some dogs are even trained to do important jobs. Many dogs help police solve crimes and search for missing people. Dogs even help people who are deaf or blind. Wolves are also smart – they have strong senses that they use to survive in the wild, however, wolves are not easily trained the way dogs are.

Nose

Dogs and wolves have a great sense of smell. A dog’s sense of smell is 1000 times better than a human’s. Many dogs use their sense of smell to help with important jobs. Dogs work for police to detect illegal drugs and find criminals who are hiding. They also use their sense of smell to help find people who are lost or missing. When there is an accident, such as a building collapse, or a natural disaster, dogs use their strong sense of smell to find people who are trapped. Wolves use their strong sense of smell to help them find prey. They can also smell and sense dangers around them.

Ears

Dogs and wolves also have a strong sense of hearing – much better than people. Dogs and wolves use their ears for more than just hearing though. Their ears also can show how a dog or wolf is feeling. Perky ears show that they are paying attention to something, flat ears, usually pointed backwards, means they are feeling angry or threatened and can warn others to stay away. Soft flat or flapping ears show a dog or wolf is happy, friendly or comfortable.

Eyes

Dogs and wolves don’t see in color like people do. Many colors, such as red, orange and yellow, can all look alike to a dog or wolf. Even though they may not see colors well, dogs and wolves do have excellent eyesight. Having good eyesight is especially important for wolves in the wild who need to be able to see prey and predators.

Communication

Dogs and wolves make many different types of sounds to communicate.

Wolves are known for their howl. Some dogs howl, but not all. Dogs are known for barking. Dogs bark for many reasons. They may bark as a warning to stay away or to let their owners know they sense danger. Dogs bark when they play, when they want attention and even when they are bored. Wolves will sometimes bark as a warning of danger.

Dogs and wolves both growl and snarl to warn predators, animals or people to scare them and as a warning to stay away. They growl when they feel threatened and are trying to protect themselves, their family and their home.

Digging

Dogs and wolves both dig. Wolves dig holes to hide food and bones to save for later. Some wolves dig to find food such as mice. Wolves also dig holes in the summer to find somewhere cool to lie or in the winter to stay warm and escape the cold. Wolves also dig underground dens as shelter for their pups. Dogs dig mostly for fun or when they smell something interesting. Dogs love to dig holes to hide their toys and bones – and dig them up again later.
