depends... but due to well being bred for herding they will sometimes nip their owners.
no dog is aggressive unless you make it aggressive. :-\ if you mean a border collie then it will only become aggressive if it is bored. if you are planning on getting a border collie make sure you have stuff to entertain it with.
Um i am not quite sure on this, but i think they might not get along. Even though collies are great pets and are gentle, Chihuahuas can get aggressive (hard to believe) . But, if you get them both around the same age(puppies) they will grow up together and might like each other. Hope i helped. :)

There are only rough collies and smooth collies. Some people call shetland sheepdogs minature collies, but they aren't.
No!, Border collies are the smartest dogs in the world!

"Mini collies" or "miniature collies" are not a recognized breed. There is a breed called a Shetland Sheepdog, which is often referred to as a miniature collie because of its resemblance to the Rough Collie. Shetland Sheepdogs are a separate breed from collies.
I have a collie my self and it is the sweetest dog in the world. It will lay in it's bed with my cats and keep them warm. I just can't tell you how sweet the are. There special dogs!
Usually collies can be kept anywhere in the world as long as they are cared for!
Bearded Collies are 51 - 56 cm tall.
No, collies do not hibernate (become partially dormant over the winter)
