My boys eat raw and have done really well on it. Miles will be 2 tomorrow and Truman is almost 1.5 years old and they have eaten raw before I even got them, when they were with their breeder. I also incorporate The Honest Kitchen "Preference" (vegetarian) line, which is dehydrated raw, plus cottage cheese, some grains, pumkpin, tripe, some supplements, and olive and salmon oil into their breakfast. Raw meaty bones are fed for dinner. They are both at good weights, their teeth are clean, coats shiny, bright eyes, and have lots of energy. I don't think they've ever had diarheea and they don't have any stomach issues. I know I can't say it's
all because of their diet, but I would like to think that at least some of it is!
As for feeding raw while traveling...I have never boarded my dogs, but when I have someone else watch them they are either on The Honest Kitchen dehydrated raw (not "Preference", but one of their lines that's not vegetarian, "Force" maybe?) or a high-quality kibble. My family that watches them is more comfortable feeding them this way. I did find a doggie daycare in Chicago though that will feed raw, including RMBs, which is nice in case I ever need to board them. As far as hygiene, I feed my boys on separate towels (1/2 bath towels, actually), that are washed in hot water in the washing machine after each use. And of course they wear their snoods! They are trained to keep their food on the towel so it doesn't get on the floor.
It takes a while to get used to feeding raw, and I would suggest doing your research so you know that you're feeding them a balanced diet (you can also sign up for Monica Segal's feeding group list, which I'm on...or I think you can pay her to formulate a diet for your dog), but once you get the hang of it it's not hard at all. Good luck if you make the switch!
