The only thing that fits into the timescale is the amoxicillin he was taking up to a week ago. He is showing all the classic severe
side effects, lethargy, vomiting, diarreah, pale gums, no bleeding anywhere though.
Could the antibiotics he was taking be the cause? It is the only thing that I can think of, but when at the vets, as it was a weekend callout, and worrying about my dog, I didn't think to ask.
He is a 5 year old boxer, weighs 35kg. Was taking one 500mg twice a day.
