..Can I just say that it's close to impossible to find a vet on a Sunday, let alone one late in the evening?
Had an emergency last April on a Sunday. It was 'round 11am when we started making calls. Took 4 hours and countless phone calls until we were able to get a hold of someone.
Everyone is saying to put the animal down. If you're not able to find a vet, that means doing it yourself, and I really doubt that most people here would be able to do it themselves.
