Dog Chapman's wife Beth was glad to blab about the new season of their show -- but quickly turned less vocal when asked about their son's recent arrest.

Tucker -- the same son who leaked those infamous phone calls to the National Enquirer -- was busted last week on a parole violation. Beth gave TMZ a little insight though, telling us she was "sorry" about him being jailed.
