Three things that are always worth sending:

A number that is wrong. Include the page and, if you have it, the maker’s current chart URL. Every row here carries the date it was read, so a changed chart is easy to confirm.
A brand that is missing. The rule for inclusion is a chart published on the maker’s own site. Retailer listings are not enough.
A breed with a published girth. Girth is the measurement this dataset is thinnest on. A citable source for one is genuinely useful.

This is not a vet line and not a fitting service. For anything about your dog’s health, talk to your vet.
