This is a very important question. The first thing you need to do is figure out if the dog has ever bitten, killed or injured an animal before. If so, he will probably be afraid of kittens. And even though your kitten may not have done anything bad yet, there are plenty of other animals around that could present a danger to it in the future.
The second thing that you should consider when trying to introduce your dog and kitten together is their age differences. You want them both to grow up alongside each other without any problems caused by their behavior toward one another during this period of time – at least until they’re fully grown adults!
If you can demonstrate convincingly (through positive reinforcement) that your puppy will only bite the kitten after it’s been introduced properly (in another room away from him), then you might be able to bring them together for short periods here and there throughout their lives as long as neither becomes too frightened or interested in chasing the other (and vice versa). This does depend on how well-behaved their personalities are regarding each other, however; some dogs may end up being overly protective toward new pets while others may become excessively possessive about them later on down the road once they’ve developed into adulthood enough to learn what jealousy looks like! So don’t take risks with someone else’s beloved pet just because you feel like having more than one cat! Do research on which breeds/types prefer interacting with strangers before bringing home
