My 10 year old bff died on tuesday;-(i had to put her down after she had multiple seizures for about 40 minutes before i got her to the vet. she was on antibiotics for blood in her stool 2 weeks before. She drank a little ocean water the day before and threw up a lot. I also noticed diarrhia 2 days before. 2 days before she ate some grass and threw that up to.Do you think she may have been dehydrated which caused the seizures? They say it might have been a brain tumor also. Her blood panel showed her white blood cell count was off and her thyroid level was 5.5. I gave her thyroxine everyday. I just am so devastated i cant stop thinking of what I could have done differently to save her life.I just wonder if i should have made her drink more water and this might now have happened.Sorry to ramble on just trying to find some answers. Any insight would be greatly appreciated.
