my ex-T had a dog that he brought one time to the office so that i could meet his dog (i had been pestering him for years). then when he moved his office to out of his home, he always let his dog join us. we would sit on the floor usually with the dog between us. his dog was older, so he was generally quite calm and content. i often found having his dog there comforting. i would bring a special treat for his dog each week which his dog definitely enjoyed. when my ex-Ts dog passed away some months after i had ended therapy, he sent me a message to let me know.
