When we had the vet give our previous yorkie Baby the Bordetella I felt terrible because to me it was like watching her get waterboarded the way they put it in her nose and her struggling. She had the coughing and lethargic symptoms too afterwards. Unfortunately we thought it was necessary because we were going to have to board her. As it turned out we didn't board her because I would not leave her while she was having such a bad reaction. We ended up taking her with us to an out of town wedding.
