It's been a long time since I have posted on here, in a way it's good because my 6 year old Golden Colby has been happy and healthy. Well she passed away in the car this morning while rushing her the the emergency vet. I'm heartbroken beyond belief. She was her normal self yesterday and last night, 5 am this morning, wouldn't get up, vomited and pooped on the floor, crying. The er vet did an ultrasound and found fluid around her heart. Every check up her heart was good, never had any health issues with her, except lyme disease. I'm sick with grief. Has anyone heard of this? We opted to not get an autopsy. I feel guilty, that I could have done something , but she didn't have any symptoms before this morning. I saw her take her last breath and it will haunt me for a long long time.
