A cat-dog mesh Yo-kai resembling a shiba dog. His body is dull orange with a cream-colored muzzle, chest, and paw tips. His inner-ear is dark pink and he has loose tufts of fur on each cheek. His nose is a dark brown and he has dot-styled eyebrow markings above each eye. His Haramaki is crimson, while his tail flames and collar orb are lavender.
Doggynyan acts like a dog rather than a cat.
Like the rest of the his team Doggynyan has a unique walk/run animation. He runs one all fours much like a dog, unlike how Jibanyan and most cat Yo-kai have the same run and walk animation.
This can be found when playing as him in (Yo-kai Watch Busters)

When being released from Crank-a-kai (Yo-kai Watch 3) :*Sniff* *sniff* "You have kibidango, bark? I'll follow you for the rest of my life, bark!" (クンクン お前きびだんご持ってるワン?一生ついていくワン!)
Once a battle when the yo-kai is defeated the yo-kai is revived with a little HP.
His Japanese name, 'Inunyan', is a combination of the Japanese word 犬 (Inu) and ニャン (nyan).
His English name, 'Doggynyan', is a direct translation of its Japanese name with exception of "Dog" being changed to the childlike colloquial "Doggy". This may have been due to the fact that the target audience is children and that is how most of them would say the word "dog" outside of Japan.
Doggynyan is based on the talking dog that accompanies Momotaro in his quest in Japanese Folklore.
It is revealed that his dog ears are a part of a helmet as seen in EP093.
Doggynyan appears in an episode of Nyanpachi-sensei/Mr Crabbycat in an all-cat class including Baddinyan, Thornyan, and Shogunyan, but suffers a dilemma over whether he is actually a cat or a dog. While played for laughs, it's a satire of a famous episode from Kinpachi-senseiwhich was about gender dysphoria
Doggynyan's sound byte says "Puppynyan" in Wibble Wobble which was probably his initial name.
