Fido shouldn't drink ANY alcohol, it can kill him!! Read the link below. There are reports of people surviving jumping out of a plane without a parachute, but I wouldn't want to try it, you get the point.
If have not poured a beer from the keg in a day or two I get a lot of foam and was pouring it on the ground (outside, my kegs are in the garage) and my dog loved it. I now pour it in a bowl for him to enjoy. It is not even more than an ouce or two but he is 200 lb dog so I figure it can't hurt him.
We had a lab a few years back that loved beer. Our beer fridge froze up once and my dad left the tap open by accident. Needless to say, the keg unfroze and flooded the basement with beer. The lab loved it. No ill effects.
I let our little kitten have a taste this weekend. She spent a few moments sniffing and wondering then took a lick...
She jumped backwards out off my lap and out of the recliner like she had been zapped by a shocker! I'm not even sure her tongue had a chance to touch the beer! And it was a malty mild too! I can't even taste any hops in it!
I haven't given any of our dogs beer that I can remember. Well, not the pair that we have today. Maybe tonight. Just a taste.
