Can alka seltzer hurt your a pet like a dog you have heard it hurts birds but can it hurt dogs I live next to a high school and some kids were throwing allka zeltzer I was walking my dog?

Never ever allow your dog to ingest any medication or remedy that is intended for humans without the explicit express instruction of a veterinarian. If you think your dog has ingested something, call your vet ASAP. You can also call poison control--they are set up both for human and animal poisonings.
