My aunt's fiance, who lost his tri collie Bogart to a car last September, is now facing the loss of his merle female collie. From what I hear it sounds like a toxin. He said last week she threw up and wasn't feeling good so they took her to the doctor but didn't get bloodwork done. She's gone downhill since and they got the bloodwork done yesterday. The results should be in tomorrow. Tonight my aunt called and said Diamond wasn't good and may not make the night. She responds to her name but can barely lift her head. I feel so bad because they just lost one dog.
