We just took a 9 day rush trip from our home in the Okanagan Valley, British Columbia, to Mt. Rushmore in our camper with our two ALD's. As we are unable to take meat across the border I was left to purchase grocery store meat and blend with veggies etal myself. I have a dream of gathering info so when travelling to different cities we might be able to find pet stores that carry raw or grain free foods.
BTW my girls travelled well, no one tried to kill anyone in confined spaces - we even snuck them out for a picture at Mt. Rushmore... a passing vehicle asked if they were ALD's and said they had a 10 month old in their back seat!
