The dog once shared by Johnny Weir and estranged hubby Victor Voronov now has TWO DADDIES once again -- the divorcing couple has agreed to joint custody of the pooch ... pending a full-blown custody trial ... TMZ has learned.
Weir and Voronov have been warring over the dog since their split. Under the arrangement, Voronov will get the dog for 1 week a month ... and when Weir leaves town for more than 2 days.
As we reported, Johnny took the dog while he was cleaning his stuff out of Victor's house -- and Victor looked on in tears. Johnny later claimed Victor used to beat the dog back when they were together.
And we thought Hollywood divorces couldn't get any more Hollywood.
