Last night our 5-year-old chocolate lab Charlie had some kind of episode. He was trying to stand/walk and couldn't, he kept falling backwards. He also released fluids from his anal glands. He looked scared and was panicking a lot. I managed to help him downstairs and outside for a toilet break, hoping that would help or at least spare our carpet from any further mess. Afterwards, he seemed better but was a still bit off. Has anyone experienced something like this before?
