Admittedly libido-challenged media exec Noah Szubski, who is suing his former girlfriend for custody of their Doberman pinscher, told a judge Tuesday that the pooch is his only companion.

The dog, a 5-year-old named Cash, “is my social life since Chelsea and I separated,” Szubski said in an attempt to prevent his ex, Chelsea Conrad, from getting shared canine custody.

He added that he is now devoted solely to the pooch.

Conrad, TV actor Robert Conrad’s daughter, has said in Manhattan Supreme Court papers that Szubski’s canine custody battle is retribution for his own failures in the sack.
