One benefit of pets being seen as property: you can take that roommate to small claims court and make her pay for property damage to cover the cost of medical bills A benefit of animal laws being passed: you can have her charged under animal welfare laws (if you can prove she knew grapes are highly toxic to dogs and knowingly fed the grape anyway, or charged as an act of negligence)
Honestly, this isn’t about whether it’s “her dog”. she caused the situation. Grapes are toxic to dogs, and her actions led directly to an emergency vet visit. Even if she didn’t intend harm, taking responsibility and helping cover the bill is the bare minimum. Refusing to do so and yelling at everyone just makes it worse.
