What You're Actually Looking For
"Mr Brown Can Moo, Can You?" is a picture book by Catherine Rayner. It's been out for years now. People searching for the PDF usually want to read it to kids or use it in a classroom setting. The straightforward answer is that there isn't an official free downloadable version from the publisher. That said, copies circulate all over the internet, and finding one is trivial. The harder part is figuring out what you're actually getting when you click through. I've downloaded several versions of this book over the years for different purposes. Most of the random file-hosting sites are junk. Some of them have scan quality so bad the text is blurry, or the pages are flipped sideways because someone fed the book through a scanner face-down. A couple were watermarked heavily. The ones worth keeping tend to come from archive.org or similar repositories where people uploaded legitimate scans of physical copies they owned. When I'm hunting for these, I skip the first page of search results. Google tends to promote ad-heavy pages and PDF-hosting spam at the top. Go deeper. Check forums, parenting groups, teacher message boards. That's where people post links to actual readable scans without the malware pop-ups and suspicious redirects.
Here's a detail people miss: some of the freely available versions are missing pages. I found this with one particular copy that had the last six spreads cut off. The book ends abruptly with Mr Brown just sitting there. If you download and it feels incomplete, try another source before assuming your device is broken. This happens more than you'd think with pirated children's books.
The Practical Issues
Running a PDF of this book through a printer is another thing. The original illustrations are full-bleed color plates. A decent home printer will reproduce most of it fine, but the dark navy blues in Mr Brown's coat come out muddy unless you adjust the color calibration. I spent twenty minutes tweaking a print job once because the copy I had was a compressed web version. The colors had been crushed during the conversion process. A higher-resolution source file makes a noticeable difference here. If you're using this on a tablet or phone, page turns can be annoying depending on which PDF reader you're using. Some apps handle landscape picture books badly. I recommend using a dedicated document reader rather than a browser-based viewer. Browsers tend to zoom weirdly on large spreads and make tap-to-navigate feel clunky.

Why The Official Route Exists
Every author and illustrator works on these books for months. Catherine Rayner's artwork took considerable time. When people rip PDFs and distribute them, the creator doesn't see anything from it. If you find yourself using this file repeatedly, or sharing it across a classroom, the honest move is buying a copy. The paperback runs around ten dollars, which is nothing compared to what goes into illustrations at this level. The library route also works well. Most public libraries carry it, and many have digital lending through OverDrive or Libby. You won't get a permanent download, but you can read it on your device for a couple weeks at no cost. This beats the legal gray area of random scan repositories and tends to have better quality anyway since libraries scan or license properly.
What I Actually Use Now
I keep a clean copy on my iPad for reading sessions. The one I use came from a library license. It's the right resolution, the pages turn smoothly, and it doesn't have any weird artifacts from cheap compression. I've shared it with other parents who asked, which isn't something I should recommend, but the point is that a properly obtained copy just works better in every practical sense. File size, readability, print quality, the whole thing. If you do go the free download route, check the file size before opening it. A legitimate full scan of this book should be somewhere in the 40 to 80 megabyte range depending on resolution. Anything under twenty megabytes is probably a heavily compressed mess. Anything over a hundred might be fine, but could also be someone's raw scanner dump with unnecessary metadata. Both extremes warrant a quick preview before committing to the download.
