I wouldn't worry, just keep the kittens and puppy seperated until the kittens are a little bigger. My daughter and I raised two orphan kittens last fall, they were about 2 weeks old when we got them. At the time we also had a large mixed breed and a 1 yr old shih tzu. When the kittens weren't being fed or tended to we kept them in a large carrier with a heating pad. As they got older we moved them to a large dog crate, then eventually let them have a room to themselves. They also had supervised time with our dogs and other cats, my shih tzu loved to clean their faces and cuddle with them..... now that the kittens are a year old they are great with all of our dogs.
