I raised Scotties and Airedales since 1973 I no longer breed but have 2 Airedales and 2 Scotties. They have so far welcomed new dogs into our home. Currently we have a dog that has been here for 6 months as owners returned to China for business. I have hardwood floors so accidents are not a problem but dogs should be house broken. We ride in the car daily or hand walk on my quiet country road I will only have one clients dogs in my care at a time. I also have the capacity to completely separate new dogs until I feel it is safe to have dogs greating themselves with my personal animals.
