Yeah, Juno has got a really shiny soft coat that is purely down to diet. But she never really got much in the way of a super fluffy undercoat if you know what I mean. I was told it was because she spends time indoors. She spends about 65% of her time indoors and the rest outdoors. She's never slept outside at night in her whole life. But that must have be down to genetics though, right? Her fur is rather short anyway.
I'll be curious to see what sort of coat Bowser develops. His parents have really fluffy gorgeous coats, sort of mid length. So I'm glad to hear that time spent indoors/outdoors shouldn't really affect it too much.
