• Destruction: Some pet owners blame their dog’s destructive tendencies on boredom, unaware that anxious and fearful dogs also become destructive dogs. Dogs chew, dig or scratch at doors and other objects in attempts to escape what they fear. The anxiety and fear centers of the brain trigger the fight or flight response — and destruction resulting from fear is usually an attempt toimg class flee whatever triggered their fear reaction.
Some dogs with separation anxiety chew on objects, door frames or window sills, dig at doors and doorways, or destroy household objects when left alone or separated from their guardians. These behaviors can result in self-injury, such as broken teeth, cut and scraped paws and damaged nails. If a dog’s chewing, digging and destruction are caused by separation anxiety, they don’t usually occur in his guardian’s presence.
"Profound fear and withdrawal of unknown cause (so called idiopathic fear and withdrawal) has also been noted in certain dog breeds, including the Siberian Husky, German Shorthaired Pointer, Greyhound, Chesapeake Bay Retriever, Bernese Mountain Dog, Great Pyrenees, Border Collie, and Standard Poodle, among others," PetMD explained. "There appears to be a strong familial component, with the likelihood of a genetic influence."
Almost every single animal on this planet works under the same principle: in order to continue receiving good things, you need to continue acting a certain way. The same concept holds true for dogs. Whenever they do something that is good, you should reward them. This will reinforce that positive behavior and cause them to continue acting that way. Eventually, they will start acting that way without requiring an award.
4. Consider changing your vet if he/she isn’t tuned in to your dog’s needs. While some vets are great with nervous and aggressive dogs, others are still very old school; they don’t listen to owners and use invasive and rough handling. There are, however, new techniques out there for vets dealing with anxious dogs. Dr. Sophia Yin has developed a program for vets that focuses on low-stress handling, which can make a huge difference in your dog’s anxiety levels. And Dogs in Need of Space has a list of vets who go the extra mile for anxious dogs; if you do want to change your vet, it’s a good place to start.
Puppy biting is normal and necessary. Puppies need to learn how to control the pressure of their bite. Allow the pup to bite your hands. When you feel pressure more than a light touch, squeal “Ouch!”, get up and walk into another room. This is how littermates play with each other. If one playmate bites too hard, the other yelps and walks away to lick its wounds. The biter learns to soften its mouth or risk losing its playmate. Loss of a playmate is more understandable to the pup than punishment.
Remember that training is an ongoing process. You will never be completely finished. It is important to keep working on obedience training throughout the life of your dog. People who learn a language at a young age but stop speaking that language may forget much of it as they grow older. The same goes for your dog: use it or lose it. Running through even the most basic tricks and commands will help them stay fresh in your dog's mind. Plus, it's a great way to spend time with your dog.
