He would also get confused, like when my other dog would nudge him, he'd bark at her, and continue barking at her even after she'd left the
room. He also had extreme hind end weakness and started urinating in the
house. These side effects
abated so slowly it was agonizing, even after we cut back on his dosage. Every day, however, he has been slightly better. Finally, at three weeks, we're putting away the plastic sheeting, and watching him play again with our other dog.
