Every veterinarian can recall countless examples of sketchy histories about a pets symptoms. Just a few examples: "no honey she first vomited on tuesday not thursday" "i don't think she ate since yesterday or the day before" "no i don't know what her temperature is"
The Daily Chart is particularly useful when there are multiple caretakers for your puppy, when children are involved in the puppies daily routine and for keeping track of any questions you may need to ask your veterinarian.
