Some serious behavioural issues are best treated with behavior modifying medication. These medications are just one aspect of an overall behaviour modification program. If your vet has prescribed medication for your dog, it is because he or she feels this is the best course of action for your particular situation. It is important that you use the medication as your veterinarian has advised. You should also keep your veterinarian up to date with any behavioural or physical changes that occur after starting the medication. Many medications used to treat behavioural issues require several weeks to reach full effect. Sometimes it is necessary to change to a different medication, or to add in a second medication for specific circumstances. If you feel the medication is not working, talk to your veterinarian before stopping the medication. Some behaviour modifying medications should not be stopped abruptly.
Sharon is currently undertaking a PhD in veterinary pharmacology, specifically in behaviour modifying medication. Hence she has a good understanding of what each medication is prescribed for, and how it may affect your dog's behaviour. However you should always ask your veterinarian directly if you want more information about the medications your dog is taking.
