Some of you may have seen my post several weeks back, however, for the OP ---> My golden retriever died from a reaction to eating spent hops Superbowl Sunday.
I know it doesn't affect all dogs, but it did mine (fwiw, i have a second golden who is usually the one who eats everything in her path, hard to say whether she consumed any that night, but she did not get sick).
And if your dog isn't affected, who's to say your neighbor's dog won't come over and try them out? I for one will lean towards the knee jerk conservative side moving forward for obvious reasons.
