Jenelle and David showed up together Tuesday to court in North Carolina in their ongoing Child Protective Services case ... but had nothing to say to our camera. As you know ... the troubled couple has been making court visits almost weekly since David shot and killed the family's dog.

Not long after Jenelle and David arrived, Jenelle's ex, Nathan Griffith, showed up with their 4-year-old son, Kaiser. It's unclear if any of Jenelle's other kids -- including 9-year-old Jace and 2-year-old Ensley -- made it to court.

As we first reported ... Jenelle and David enrolled in couples therapy in an attempt to get their kids back. David will also undergo a psych evaluation to determine what is at the core of his anger issues.

All of Jenelle's kids were removed after a judge decided there were serious issues with the couple that put the children at risk.
