How To Introduce A Puppy To A Kitten?

I had a kitten and I want to introduce my puppy. So, I was wondering how I should do it?

I have a 6 week old Pitbull/Mastiff mix who is house trained but for some reason does not like other dogs. He will go right up to one though, lick them on the nose and sniff around their legs….but doesnt make friends with any of them.

So i’m thinking about getting another smaller dog that he can play with because if they are close enough together that means there isn’t an entire kennel full of dogs at once which could potentially get him into trouble when im away from home . And also be able to keep an eye on the two while at work…..however..

Pitbulls are territorial so its important to pick out ONE dog in particular to begin with or else you may end up choosing the wrong dog altogether in future attempts…and thats what happened in my case unfortunately :p Now im stuck 🙁 Any advice would be greatly appreciated! This is all very new territory for me so i dont really know where i stand lol 🙂
