My two have different coats, but both are very soft. Jazzy's is a bit heavier; Keoki's is thinner, more sleek. But both are wonderful to pet. Jazzy's seems to feel more "huggable"0- you know, smoosh your face into her neck, LOL – while Keoki's you just want to stroke and stroke.
As for the food, I've fed my dogs what some call "junk" food my whole life and I've always had healthy dogs with beautiful coats and long lives. It really is a to each his own situation, IMO,and no one should be criticized for those choice as long as the dogs are healthy.
My B's have been on Purina and Kirkland and have done beautifully.
I currently have them on Merrick's Turducken -- only because Gypsy {14} was beginning to not eat well so I was adding canned food to all their food {you can't give just one the good stuff} but that was getting pricey, and with the Merrick's I can add water AND feed a bit less so the cost comes out about the same as my other foods. So far she eats the Merricks with enthusiasm, and the B's like it too.
