How to Discourage Dogs from Chasing Cats?

Buddy’s husky killed a few cats.
But they got into his dog run.
They had 2 cats too.
The cats knew the limits of his dog run/cable.

As he got older,he became friends with both cats.
Was strange...

Kinda like our old lab, he is getting up there in the years, and just don't care anymore, when he was younger he hated cats, now we have an inside cat and they get along fine.
The inside cat, is still young about a year old male, stray that adopted us last winter.
Apparently he liked fighting with everything in town, and was not too good at it, he always came in, beat up, hair missing, limping etc.
One day he came in with his eye half ripped out.
A trip to the vet to remove his eye and nuts calmed him down.
