What is most useful to send
Corrections come first. If a page gives a weight, a date, a price or a legal rule that you know to be wrong, say which page it is, quote the sentence, and add a link to the source that shows the right information. A link to a breed standard, a club page or a government website lets an editor check the point in minutes rather than days.
Local knowledge is the second most useful thing. The province pages list regional clubs, SPCAs and rescue contacts, and those details change: a club launches a new website, a rescue stops taking applications, a city changes its licensing rules. If you are close to one of those organizations and see something out of date, a short note helps every reader in your region.
Broken links are worth reporting too. Club and rescue websites move often, and a dead link on a page about finding a rescue dog is more than an annoyance.
Questions that belong elsewhere
Some questions are best answered by someone who can see the dog. If your Cavalier is coughing, tiring on walks or scratching at its neck, your own vet is the right first call, and a referral to a board-certified veterinary cardiologist or neurologist may follow. The health testing guide explains what those specialists look for, so you can go to the appointment with the right questions.
Questions about a particular litter, a puppy's pedigree or a waiting list are best put to the breeder or to the breed club. The national Cavalier club keeps a breeder directory, the Canadian Shetland Sheepdog Association lists its member clubs, and the CKC Puppy List can be searched by breed and province. The breeder guide and the Sheltie puppy guide list the questions to ask them.
What happens to your message
Messages are usually read within a week, often sooner. A correction that checks out is made on the page, and the date at the top of that page moves to show it was revised. Not every email gets a long reply, but every correction with a source gets looked at.
Your email address is used only to reply to you and is not added to any mailing list. The privacy page explains how long correspondence is kept and how to ask for it to be deleted.
A useful subject line saves time on both sides: the page name and one word, such as "Grooming: correction" or "Alberta: club tip".
