You know that choking/gagging sound Cavs sometimes make?almost like a cough. During last night Maddy came into our room doing this & obviously in some distress. It doesn't happen very often but it unsettled her & she came to me several times afterwards even though she was fine - I think it was for reasurance? When it does happen I usually gently rub her throat & talk to her in a calm way, is there anything else I should do?
