Dogs & Cats help please

I posted this before, I'm hoping someone can help. I want to adopt this cat
but my dog is grown and my previous attempts to introduce him to cats (2 at
different times) he would tree and they finally ran off (they were strays
too). Is it possible to successfully introduce a grown dog (inexperienced
with cats) and grown cat (experienced with dogs)? I would not have the cat
indoors, but the dog is most of the time.
TIA
