Leaves in six weeks? It sounds as if you are going to be successful. If they are not covered by a plastic bag, try to mist them with a hand sprayer each day. Don't worry too much about them loosing their leaves over winter as all roses will do that anyway.
Have a look at this link for the Dog Rose (Rosa canina).
The hedgerows alongside my garden have many Dog Roses and i find tiny examples growing in cracks in the paths or brick walls. I tend to pot them up until I decide where I can place them. I have no experience of taking cuttings of the Dog Rose but they clearly grow well from seed. I have succeeded in growing Rosa rugosa from seed although this is a fair bit slower to reaching flowering stage than taking cuttings. I took a rose hip in the autumn, opened it up and allowed the seed to dry for a few days, inserted the seed in a plastic bag in some sharp sand and left in the fridge for six weeks to immitate the winter (stratification), sow seed in seed compost and wait for the seeds to germinate. One rose hip provided me with eight strong and healthy plants a couple of years later.
