Our dashchund is on Prozac now because of some very aggressive behavior toward family members (he growls and snaps any time he is moved or touched--more so at night and especially when touched with feet accidentally or otherwise). This behavior initialy got better after starting the Prozac, but now has gotten worse. 1)Could the medicine have made it worse? 2)Any behavioral/training suggestions to help this situation without drugs? We plan to start a family soon and this behavior cannot happen around a baby.
