Crystal C,

You really do need to take the dog to a vet ASAP!!! Gulping and crazy eyes sounds like he might be choking or gulping for air!!! It sounds like he might have a damaged trachea. This could result in some serious problems including difficulty breathing and swallowing. This is definitely a situation that needs a vet diagnosis rather than supplements, especially since it started after an incident involving injury. Please rule out any medical problems!
