I was made aware of this Russian poem today Ivan Krylov. Elephant and Pug. Translated by unknown author and a saying about small dogs being aggressive (and as all sayings it is really about people):
“маленькая собачка - до старости щенок”
“A small dog is a puppy until old age.”
“Pieni koira on pentu aina vain”
Words to fill our word bank are:
до - here: until - asti, saakka
старость - old age - vanhuus
щенок - puppy - koiranpentu, pentu
