How do I weigh my dog accurately at home?

Weigh yourself alone first, note the figure, then pick up your dog and weigh yourself again holding them, and subtract the first number from the second to get your dog's weight.

Repeat this two or three times and average the results, since a wobbling bathroom scale reading can vary slightly between attempts.

Some digital bathroom scales can weigh a larger dog directly if the dog will stand still on the platform, though accuracy can be inconsistent, especially for dogs over about 30kg on a scale designed for human use.

A dedicated pet or veterinary scale gives more reliable, repeatable results, and many vet clinics allow walk in weigh ins between appointments free of charge.

Weigh at a similar time relative to meals and toilet breaks each time, since a full stomach or bladder can add a noticeable amount to the reading, particularly for smaller dogs.

Use the same scale each time you track a trend, since different scales can read slightly differently even when both are reasonably accurate, and switching between them can make a stable weight look like it is drifting when nothing has actually changed. Write each reading down with the date, since a short list of numbers is far more useful for spotting a genuine pattern than trying to remember how a reading compared to the one before it.
