ZD,
This line is not true.
“he asked if they were allowed in other houses of worship”
Doe this apply to a tzelem as well? Because they are allowed in other houses of worship and HIR, and I doubt either Rav Pam or Rav D Cohen would say they are allowed in a shul because they are allowed in other houses of worship.
That IS NOT the reason that service animals are allowed in shul.
Yes I have seen them in shuls. Charedi shuls. In shuls not owned by the Rov and in shtiblech as well.
