"He seems different" is an understandable concern, but it leaves a veterinarian with many questions. A useful new-dog routine note records what happened, when, and in which setting, while separating observations from explanations. Start a brief baseline after adoption and bring the available history to the clinic. Do not delay a call about a concerning change while collecting a longer log; an emergency needs care, not a completed form.
Begin with what is known and what is missing

Write the adoption date, estimated age if supplied, current food, and the source of each detail. Label estimates as estimates. Keep shelter records and current veterinary instructions together, but do not copy an old prescription into a new care plan without confirming that it still applies.
Ask the clinic which observations would be useful for this particular dog. Your dog's age, health history, and current concerns may change what the veterinarian wants recorded. A generic log is a starting format, not a list of tests you must perform at home.
Use an ordinary notebook or a shared document that the actual caregivers can maintain. If a paper format helps, the Pet Health & Wellness Log Book (paid link to Amazon) is an optional example; its listing includes sections for a pet profile, medical records, and vet visits. A logbook's prompts do not establish what is medically normal or replace your clinic's instructions.
Describe an event without giving it a diagnosis

Compare "refused the walk" with "stopped at the building entrance, looked toward the delivery cart, and returned inside with me." The second note preserves information. It does not decide whether the cause was discomfort, uncertainty, noise, or something else.
For meals, record what was offered and what you observed the dog eat. For toileting, describe the event you actually saw. If you did not see it, write that. Avoid converting a partly observed event into a precise quantity or confident conclusion.
Keep the wording neutral when different people contribute. Replace labels such as lazy, guilty, or dramatic with behavior and context. This is not about writing professionally; it is about giving the next person a usable account instead of an interpretation they cannot verify.
Make the log small enough to continue

Use these fields: date and time, food or activity context, observation, prescribed care completed, action taken, and question for the clinic. Record completion only when the responsible caregiver knows a task was done. Medication uncertainty belongs in a call to the prescribing clinic, not a guessed entry.
Hypothetical entry: "Tuesday, evening: ate some of the offered usual food; amount not measured. Moved away when the dishwasher started. Water available. Question: which changes should trigger a same-day call?" This is an example of a note, not a normal-health standard or advice to wait through reduced appetite.
If a brief video would help, capture only behavior that occurs naturally and can be recorded safely. Do not provoke a reaction, force exercise, or repeat a painful movement for the camera. Ask the clinic how it prefers to receive material.
Turn the notes into a focused appointment summary

Before the appointment, summarize the main concern in one or two sentences. Add when it began, whether it is changing, and what action you have already taken. Bring the underlying notes and records in case the veterinarian needs detail.
Cornell's emergency guidance distinguishes serious emergencies from problems suitable for urgent care. Trouble breathing, collapse, or a suspected serious exposure should not wait for a routine appointment. Contact an emergency veterinarian promptly for direction. Do not use a log to reassure yourself that a serious sign can be watched indefinitely.
End the conversation by writing down the clinic's instructions: what to monitor, when to contact them again, and how to seek help after hours. The payoff is a shared plan grounded in observations. Your notes help the professional assess the dog; they do not replace that assessment.
Pet Health & Wellness Log Book (paid link to Amazon) — The listing describes sections for pet profile, medical records, veterinarian visits, grooming, and pet-sitting notes.
Use it only to record observations and current professional guidance. Ask the clinic what information is useful for your particular dog, and do not delay care for a concerning sign.
