Hi again,

Thank you all so much for your responses. I see now what you mean
about the crate. I'll simply pick him up and put him in his crate with
a toy (we have some toys specifically meant to be soaked and frozen,
and no shortage of PB).

Avoiding the situation altogether is a good suggestion. I love to be
down on the floor with him, but you may be right.

I'll also forward the this link to my fiancé so she can see it.

Thanks again.
