some dogs never have problems to where they have to be cleaned...sometimes, if they get inpacted, they can rupture, this happened to my moms shih tzu, when i was driving her down to SC from Illinois(a 14 hour drive), we were only a few hours from her house, and they ruptured, and you talk about a stinking mess and I had to smell that for about another 7-8 hours..not pleasant |
