A dog weight tracker template for your veterinary conversation.

Copy a log you can keep adding to

Use a notebook, private note or spreadsheet. Create one record per dog and add a new entry for each measurement rather than replacing the previous number. ASPCApro’s weight-monitoring form uses dated entries to follow weight over time; the worksheet below adds measurement conditions and uncertainty for your veterinary conversation.

Copy this setup section once. Ask your veterinary team to fill any unanswered questions about frequency or technique rather than choosing a schedule from the example entries.

• Dog’s name: ______
• Reason for keeping this record: ______
• Veterinarian’s weighing frequency: ______
• Agreed scale or location and weighing technique: ______
• Agreed timing or other measurement conditions: ______
• Changes or symptoms the clinic wants reported: ______
• Next review date, if agreed: ______

Repeat the entry below at each planned weighing. In a spreadsheet, use these fields as column headings; in a notebook, leave space for the next entry. Keep the record yourself and share it directly with your veterinary team.

• Measurement date and time: ______
• Weight exactly as displayed: ______
• Unit shown, such as lb or kg: ______
• Scale or location, with a specific identifier if known: ______
• Method and conditions, including harness or other equipment worn: ______
• Timing relative to the usual routine, if known: ______
• Record status: measured / not measured / uncertain
• Comparison label: same setup / changed setup / setup unknown
• Context since the previous entry, with dates where possible: ______
• Source of the reading, such as clinic record or your own observation: ______
• Question for the veterinarian: ______

Agree on a repeatable weighing setup

Ask your veterinarian how often to weigh your dog and which technique is suitable. VCA’s veterinary nutrition guidance recommends using the same scale and consistent timing to reduce measurement variability. That principle does not mean every dog needs daily weighing.

1. Confirm where weighing will happen. If home weighing is impractical, ask whether the clinic can arrange scale visits.
2. Follow the technique your veterinary team demonstrates. Do not lift a heavy or distressed dog to obtain a reading; ask for a suitable alternative.
3. Use the agreed setup when possible. Record changes in scale, timing, method or equipment rather than trying to make unlike readings look identical.
4. Write down the displayed number and unit before leaving the scale. If a reliable reading was not obtained, record that instead.

Separate a changed reading from a changed setup

Use the comparison labels below as filing aids, not medical judgments. They show your veterinarian which entries were collected alike and which need more context. A changed setup does not prove that a weight change is a measurement error.

• Same setup: the recorded scale, method and relevant conditions match the previous entry. Keep both readings for review without labeling the change good or bad.
• Changed setup: a different scale, location, method or other condition was used. Keep the reading and name the difference.
• Setup unknown: an older record lacks measurement details. Preserve what is documented and mark the rest unknown.
• Not measured: a planned weighing did not happen or no reliable reading was obtained. Leave weight empty and record the reason; never enter zero or copy the previous weight.

These fictional entries demonstrate the format, not a recommended weighing interval. The numbers are examples only and do not indicate a healthy or target weight.

• September 3, 2026, 9:10 a.m. | 18.4 kg | Clinic floor scale A | Harness removed; meal timing unknown | Measured; first entry | Source: clinic record
• September 17, 2026, 4:30 p.m. | 41.0 lb | Different clinic’s floor scale | Harness on; meal timing unknown | Measured; changed setup | Question: should the next reading use scale A?
• October 1, 2026 | Weight blank; unit blank | Planned clinic visit missed | Not measured | Next step: ask the clinic when to reschedule

When combining older records, sort by measurement date, not the date you copied them. Preserve the original unit and displayed precision. If you add a converted value, put it in a separate, clearly labeled field and retain the original. Mark missing dates or units as unknown and ask the source clinic to confirm them.

Add observations without deciding what caused the change

Weight alone does not establish body condition. AAHA’s nutritional assessment guidance considers body weight, body condition, muscle condition, history and a physical examination together. Leave interpretation to your veterinarian rather than assigning a target from a breed table or treating a lower number as an improvement.

Keep context factual: note appetite, thirst, vomiting, diarrhea, energy changes, and any changes in food or feeding routine. PDSA advises reporting accompanying symptoms when a dog loses weight. Write what you noticed and when, such as “left part of breakfast on two mornings,” rather than guessing a cause.

Bring the full record and a short question list

Keep the entries intact and add a short summary above them: the date range, any changes in weighing setup, missing measurements and observations you want reviewed. Bring the original clinic readings where available, rather than only a chart or a calculated difference.

• Which readings are useful to compare, and which need checking?
• What do the measurements mean alongside your assessment of body and muscle condition?
• Should we change the weighing location, technique or frequency?
• Which changes or symptoms should prompt a call before the next review?
• When should I send the updated log, and how would you like to receive it?
