How to block a website on every device in your house

Blocking a site in one browser is easy to undo. Blocking it at the network level stops it in every browser and app, on every device, even in private mode.

Short answer

In Sheepdog Filter, open the Allow & block tab, type the website (for example example.com) under Block, and save. It stops loading on every device set up for that child, in every browser and app, within a minute, including all its subdomains. To block a whole category instead, use the switches on the Blocking tab.

The quick way

  1. Open your Sheepdog Filter dashboard and choose a child (or Home Wi‑Fi for the whole house).
  2. Open Allow & block.
  3. Type the website, like example.com, under Block, and save.

It stops loading within a minute, on every device for that child, in every browser, in private or incognito mode, and inside apps. Blocking example.com also blocks www.example.com, m.example.com and every other part of it.

Blocking a whole kind of site

Usually you don't want to block one site, but all of them: every gambling site, every adult site, every "unblocked games" mirror. Use the switches on the Blocking tab instead, and our lists keep up with new sites for you.

Why not just block it in Chrome or Safari?

Browser settings only cover that one browser. Kids switch browsers, use the in-app browser in TikTok or Instagram, or open a private window. A DNS filter covers all of those at once. See what is DNS filtering.

Blocking a website on just your router

If you only want it blocked at home, set Sheepdog Filter on your router and add the site to the Home Wi‑Fi list. See home Wi‑Fi parental controls.

Questions parents ask

Can I block a website for one child but not another?

Yes. Each child has their own Allow & block list, and their own devices follow it.

Does it work in incognito or private mode?

Yes. Private browsing hides history, but it still has to look the site up, and that's where the block happens.

Can I block just one page of a site, like one YouTube channel?

No. A DNS filter blocks whole websites. For YouTube, use Restricted Mode or block YouTube entirely.
