Jennifer Aniston and Justin Theroux have reached an agreement over custody of their dogs.

The former couple split last month after almost three years of marriage and have finally resolved the biggest dispute in their break-up by coming to an arrangement about the care of white shepherd mix Dolly, terrier Clyde and pit bull Sophie.

A source told America's In Touch magazine: ''They've always referred to them as their children.

''It was the biggest bone of contention in the split.''

The 46-year-old actor also has another pit bull terrier in New York and has ''made an arrangement for visitation'' for Jennifer, 49.

Neither the 'Leftovers' actor nor the former 'Friends' actress have spoken about the split since they released a joint statement on the end of their two-and-a-half-year marriage following increased speculation about the state of their marriage.

They said: ''In an effort to reduce any further speculation, we have decided to announce our separation. This decision was mutual and lovingly made at the end of last year. We are two best friends who have decided to part ways as a couple, but look forward to continuing our cherished friendship.

''Normally we would do this privately, but given that the gossip industry cannot resist an opportunity to speculate and invent, we wanted to convey the truth directly. Whatever else is printed about us that is not directly from us, is someone else's fictional narrative. Above all, we are determined to maintain the deep respect and love that we have for one another.''

Meanwhile, it was claimed their split was caused by the growing distance between the pair, as Jennifer spent her time in LA whilst Justin resided in New York.

A source said: ''Jennifer is more comfortable in Los Angeles with her close-knit group of friends. But Justin doesn't feel as at home in LA, nor with Jennifer's friends, he loves New York, and the edgier crowd in the city.

''As they spent more and more time apart, their problems became bigger. He's very focused on himself and his craft. And Jen is not the easygoing girl she wants the public to think she is. She isn't as happy, and she is far more complicated.''
