I really like dogs or cannis famillaris as they are called by scientists. They are actually decended from wolves!
I love dogs - we have three@!
That's cool! Your dogs are acutally related to gray wolves not modern wolves. 
What is the difference?
Wolf
The wolf ("Canis lupus"), also known as the gray/grey wolf, timber wolf, or tundra wolf, is a canine native to the wilderness and remote areas of Eurasia and North America. It is the largest extant member of its family, with males averaging and females . It is distinguished from other "Canis" species by its larger size and less pointed features, particularly on the ears and muzzle. Its winter fur is long and bushy and predominantly a mottled gray in color, although
but their turnover has been high, and modern wolves are not the lineal ancestors of dogs. Although research had suggested that dogs and wolves were genetically very close relatives, later phylogenetic analysis strongly supported the hypothesis that dogs and wolves are reciprocally monophylic taxa that form two sister clades. This suggests that none of the modern wolf populations are related to the wolves that were first domesticated and the wolf ancestor of dogs is therefore presumed extinct. Recent mitochondrial DNA analyses of ancient and modern gray wolf specimens supports a pattern of population reduction and
