You could MAKE an "imatation" E-collar for tonight!

Smokey (the Dawg) came back from the Big Snip wearing a Rigid Plastic
*WIDE* collar which fit rather around his neck
and fit between the base of his skull (top of his neck) down to
his shoulders (bottom of his neck.

Result was he could NOT "turn his neck/head" - but there was nothing
"hanging out" for him to bump into things.
Totally ruled out him getting "back there" with his mouth!

Point Being -
Get some thin Cardboard - maybe a frozen dinner box...

CUT it into a long "strip" - the proper width to go around his neck
and taking up the full lenght of his neck...

WIND it around his neck - - but let him *breathe* ...
Should go around his neck almost twice to be "stiff" enough.

Then TAPE it to itself so it won't unwind ...

Walla - "Hard Collar" which "ought to" prevent him from turning his hear/heck
enough to to da any *lickin* "back there".

They make and sell these things - but I CAN'T find a darn picture;
and can't remember the Brand Name on the one Smokey used.

Good Luck!!
