We always had dogs growing up, I pet sat all the time in college and then I adopted my Theodore who just passed last year, at the ripe old age of 21! I didn't really travel much the last 3 to 4 years of his life for fear something might happen while I was gone and he had some special needs. I chose not to get anymore pets after losing him so could travel but there is certainly a void. I have a lot of experience working with dogs that have "strong boundaries" or are "enthusiastic." I'm also quite strong and can handle big dogs. I have the utmost respect for you knowing what is best for your pet and will follow any instructions to the letter.
