If it's good enough for me it's good enough for my dogs.
Strangely they don't like Red Wine but love Saki.
Chewtoy the cat likes Cognac.
No accounting for taste.

It's actually very good stuff and does seem to perk them up when they're hot and tired. You mix up a quart and let them drink 1/4 of it before they start, and then sip the rest throughout the working period.
