Spend time with your guinea pig everyday , etc, grooming, rubbing , ...and so on .
you should never put a guinea pig with a chinchilla

no
it really depends on the guinea pig, some get along fine with friends some don't
Yes, i bought one Guinea pig and added another around the same time, and they get along great.
A rabbit
This depends on the personality of the guinea pig and the ferret, they could but they could not.
No, I doubt it. I do have a friend who has a rabbit and guinea pig in the same hutch but guinea pigs are more friendly to there own species; especially if they're from the same litter.
Every guinea pig has their own personality, it is impossible to tell which guinea pigs they'll get along with and not get along with.
Dogs and guinea pigs usually don't get along well as in the wild the guinea pig is usually preyed upon by animals such as a wild dog. you should keep the guinea pigs away separate from your dogs. There have been times however when a dog and a guinea pig do get along well.
It depends on the dog and how it acts with others
It is spelled "guinea pig". You got it right! :)
