The twin will keep the aisle more open - at all times. If necessary and my daughter wanted to travel - it would be possible to put foam down and sleep in the aisle (Remember all it has to be is better than the tent she uses now :) I have an AKC ILP number for the rescued Golden so that I have shown him in Obedience and Rally. The two English Cocker Spaniels are finished AKC CHampions - a mother and her son. I have also worked with them in Obedience and Rally. The son is still a work in progress and I don't train as much as I should. The fourth dog is a Havanese that I rescued 1.5 years ago. He is just now two. I had never had a smaller toy breed before but had read up that the Havanese were good with people, children and other dogs - something that can't be said about all the toy breeds. I wanted a smaller dog to take into the healthcare facility along with the Golden. Anyway Remi has a few fear issues from his being a puppy mill auction rescue but his friends at the HCF have helped socialize him a bunch and from the beginning he had one trait nailed - the "I will sit in your lap or next to you on the bed for as long as you want me...." And look at you with big sad brown eyes... I don't have to tell you that trait makes him a very popular visitor.
