It's "wolves", incidentally. But Draco is correct...there really is no way for a domestic animal or even a human, in early 20th century Britain, to encounter a wolf. Wolves disappeared from the British isles by the mid 1700s (see this reference: https://ukwct.org.uk/files/disappearance.pdf).

So it would not be accurate for the characters of this movie universe to be encountering any wolves in London or the outlying countryside. Unless they were visiting a zoo in the city.

And if you mean "in the character's history", that would be an unlikely thing too. There wouldn't be the domestic cross-breeding (wolf-dog) thing in Britain that was (and remains) so fascinating to a fringe element of people in the Americas, and certain other places around the world. In other words, it just wouldn't work.

How would a character from this universe ever encounter a wolf though?

i mean not as a char but in the char's history,

There really wouldn't be any way to incorporate a Wolf into the movie universe. It's about domestic dogs in London after all, not wild animals.
