Maisey is tolerating the Prozac well, which is to say there have been no adverse side effects. It will take a month to see if it has therapeutic value for her.
Other measures we have taken (sealing off our very loud mailslot, using a "DAP" pheromone diffuser, and lots and lots and lots of training and positive reinforcement) have helped her come a long way. The awesome thing is that Gypsy is a better adjusted dog as well, because she is experiencing all of these things as well (with the except of the medication).
If you have a dog that suffers from anxiety, I highly recommend a DAP diffuser.
Dog Appeasing Pheromone (DAP) mimics the properties of the natural pheromones to reduce or eliminate stress in dogs of all ages. Dog Appeasing Pheromone has a relaxing effect for both the young and adults dogs. It is an effective natural way to help your dog cope with new and fearful situations such as fireworks, thunderstorms, holiday stress, traveling or moving to a new environment.
We've been using a DAP for about six weeks now. We can't smell anything, but the dogs sure do. We noticed a change in behavior recently (they were both sort of skittish and easily agitated) and we realized we were a week overdue in replacing the DAP refill. A few hours later, things were back to normal.
If you decide to give a DAP a try, shop around for the best deal online, especially when it comes to replacement cartridges.
