Can dogs take lamictal for separation anxiety?

Never give a dog or cat human medications for anything. Check with your Veterinarian. There are several mild medications available in Pet Stores or Feed Stores. Try fixing the problem first. Take your dog on daily walks up to 45 minutes long (on leash only). Do things with your dog, such as obedience classes, etc. Your pet should calm down with adequate exercise for the mind and body. Also along with this, try putting your dog in a crate but slowly get him or her use to it. Put the crate in the house and just leave the door open, put soft bedding in there and toys. At night close the door and keep your dog in the crate. Pretty soon that will become your pet's sanctuary, their own little cave of privacy and security. So when you have to leave your pet alone, try putting them in the crate and see how that works out but do the walks and classes too.
