A dog is a mammal in the order Carnivora.

Dogs were domesticated from wolves as recently as 15,000 years ago. New evidence suggests that dogs were first domesticated in East Asia, possibly China. Over time, the dog has developed into hundreds of breeds with a great degree of variation.

Dogs, like humans, are highly social animals and this similarity in their overall behavioural pattern accounts for their trainability, playfulnes and ability to fit into human households and social situations. This similarity has earned dogs a unique position in the realm of interspecies relationships.

The loyalty and devotion that dogs demonstrate as part of their natural instincts as pack animals closely mimics the human idea of love and friendship, leading many dog owners to view their pets as full-fledged family members.

The common name for the domestic dog is ‘Canis familiaris‘, a species of the dog family ‘Canidae’. The dog is generally considered the ‘first’ domesticated animal.

Dogs can differ in appearance, function, temperament and size. Some small dogs can weigh as little as 1.5 pounds, whereas some larger dogs can weigh as much as 200 pounds.

You can train your dog with that.

Also you can use this app as a dog repeller.
