The pair, while an unlikely duo, got along surprisingly
well during their two-day visit, according to Pearl’s
owner, Vanesa Semler.

"For me, [it] was a huge, pleasant surprise from day
one because Reggie is like Pearl in [a] bigger size,"
Semler said. "He is so gentle, so friendly."

Reggie’s owner, Sam Johnson Reiss, said the Great
Dane is more of a people person but enjoyed the
playdate.
