Not all dogs will respond favorably to anxiety medications and other anxiety products. Some may become lethargic while others may not stop their anxiety symptoms. However, for some dogs these treatments can work wonders. Here are some of the best choices for anxiety relief, from medications to treats and even products your dog can wear that help them feel safe and relaxed.
Separation anxiety or separation distress, as it is often called, can prompt affected dogs to:

I adopted a rescue dog about four months ago. She is a year old now and is anxious and destructive when left alone in the house. She demonstrates excessive salivation and has been very destructive. As a result, she is now crated, but is still anxious. We are beginning to work on behavior modification training along with Reconcile [a drug prescribed for separation anxiety]. My question is, do you think that adopting a second dog would reduce her anxiety? Can the anxiety be related to loneliness or boredom and helped by a dog friend? I am very torn because I don’t want to end up with double the trouble, instead of helping the problem. Thanks so much for any input you can offer. This rescue dog had such bad anxiety — until he met his new baby brother 🐶🐶💕

Quiet time will be important for your new Chessie in the first week. Because of his nervousness and anxiety, he will get worn out fast. His recent past may include a shelter stay which has worn him out with worry. Despite your excitement, try and resist inviting friends and relatives over to visit him. Give him time to get used to your immediate family and resident pets only. If the dog does not solicit play or attention from you, let him alone to sleep or establish himself. Believe it or not, we don't want you to force him to play at first! Separation anxiety is often wrongly suspected when there is destruction or barking simply because these behaviors only happen when the dog is alone. Barking and destruction often occur out of boredom. One determining factor is whether the behavior begins immediately after leaving (separation anxiety) or much later during your absence; a video camera will help resolve the mystery. Separation Anxiety is a common behavior problem but it has very serious ramifications for both the dog and caretaker. It also appears to be more prevalent among shelter, rescued, or otherwise re-homed dogs. As foster families and new adoptive families we have to help our dogs from developing separation anxiety. One way is to not fall into the trap of feeling sorry for our “rescued” dogs and the desire to give them an abundance of attention and everything they want. Don’t do this to your dog. Separation anxiety is also common among rescue and shelter dogs because it is a common reason for surrendering a dog due to barking complaints from the neighbors, the damage it can cause, and the expense of time and money in the training. Separation anxiety, like fear aggression and phobias,is a fear-based behavior. Harsh punishments, yelling,ostracizing and standard obedience training will notwork to cure separation anxiety. Punishment will makeit worse by raising the dog's overall anxiety andthereby contributing to the problem.
