Pups chew to ease their gums during the long teething process and also to explore their world. This could mean chewing up your things, which could include your house! It's also potentially dangerous, as paints and varnishes can be toxic, while splinters can damage their tender digestive tracts.
Disciplining your little chewing pooch isn't as easy as it sounds. To properly discipline your pup, you need to catch her in the act. A puppy doesn't associate being disciplined for things he did even a few moments before, but for the things he's doing now. Upon catching your pup in the act, give a firm, loud "No!" or "Drop!" command. You can also guide your puppy away from the window frame by grabbing his collar firmly-yet-gently or picking him up and removing him from the area. Use a loud, disciplinary voice that will startle him and make him realize what he's doing is bad and unacceptable. Never smack or spank your pooch for the act; pups don't react to negative reinforcement.
When you catch your little guy in the act, give him a suitable chew toy after the "No!" or other command. Suitable chew toys include durable rubber chews, pig ears or rawhide bones, as long as they're the right size for your pup's mouth. Puppies are much like human babies, telling them not to do something is only part of the solution. You need to give your pup an alternative.
Toys and Boredom
While many pups will chew the window frames and other surfaces in your house while they're teething, an older pup may be doing so out of boredom or the lack of appropriate toys and playtime. Many dogs have an insatiable urge to chew. Chewing works their jaws and helps naturally keep their teeth clean. Give your pooch a variety of chew toys and other toys to play with and keep themselves occupied. At first, praise your pup lavishly when she's playing with her toys. This will let her know that playing and chewing on the right things is encouraged and a good behavior. He'll more likely go to his toys when he knows that it's a good thing, even when he's bored. You can also step up your exercise routines with your pup to help release built-up energy. Walk a few minutes longer or have some hardcore playtime every day.
To help curb that urge to chew on your window sills, apply taste repellents. These are available at big box stores and pet supply stores. Taste repellents are normally sprays that have a bitter taste. Cayenne pepper -- or other capsaicin-containing products -- also work because they burn the tongue.
