Why did Mrs. Pumphrey make a frantic call to Mr. Herriot?

Answer:

Mrs. Pumphrey had a dog named Tricki. Indirectly she was responsible for the dog’s illness. She gave him little extra between meals i.e.. male cod-liver oil, etc. He was not given any physical exercise. So the dog fell ill and started vomiting also. It made Mrs. Pumphrey so much worried that she had to call the veterinary surgeon, Dr. Herriot for his treatment.
