Two screenshots from the app: the article list with its search field and category filters – and an open article, from the title into the body text.


From a keyword to a finished article: how you get to the answer that matters right now.
The topics sit above the list as pills: daily life, behaviour, health, training. One click shows that topic only; «All» takes you back to the whole collection.
The search field filters with every letter – no button, no waiting. Upper and lower case and accents make no difference; it searches title, lead-in and topic. If nothing matches, the page says so; an ✕ clears the field again.
Every article starts with topic, title and a short lead-in. Then comes the text in plain language, without jargon. Some articles include pictures or a video.
Without an account you read the beginning of every article; for the full text you create a free DOGSY account. Safety-related articles are exempt: «Blaualgen: Gefahr für Hunde am Wasser» (blue-green algae: a danger for dogs at the water), for instance, is there in full, with no sign-in.
Once you're signed in, DOGSY remembers which articles you have read to the end: the green tick «Gelesen» (read) appears in the list, and you can filter by read and unread.
Three situations in which the articles help in everyday life:
«How long may my dog actually be left alone?» Instead of clicking through forums, you type a keyword into the search field and have an article on it within seconds – in plain language, and with the clear note that it is no substitute for veterinary advice.
You're about to meet a dog you don't know, and you're already on your way? Safety-related articles are there in full without an account – you can read them en route instead of creating an account first.
DOGSY comes in 44 languages. Articles appear in your language as soon as their translation is ready – otherwise you see the German original.
Reading costs nothing. All the full text needs is a free account.
The «Explore» area brings together a guide to dog-friendly places, events and knowledge about dogs – free for all Dogsyaner.
