I could never stand to bathe Sharav in my bathtub.
I tried doing it a few times in our Tel Aviv apartment, and it was really traumatic – he was miserable and I was miserable.
I agonized over paying to bring him somewhere to get bathed professionally, since it seemed like such a waste of money and so inconsistent with my values, but eventually gave in, and was very happy with the result.
After that, usually I paid to get him bathed whenever I traveled and needed to board him, or sometimes when I was preparing for a houseguest and wanted him not to smell like dog.
