Cavaliers are lively and curious.  They love to run to see other animals, people and to simply chase a butterfly or squirrel.  Remember, they are a spaniel which comes from the hunting family.  You will not be able to trust your new puppy to stay in his yard on his own.  You will need to provide a safe place for your new family member to play and run outside.  ALWAYS keep your Cavalier in a fenced in area or on a leash. 

Do not let your new family member become a statistic. 

Cages

We recommend a "safe haven" for your dog. This is often a cage. It should be just large enough for the dog to turn around. Cages should have at least 2 sides covered to provide privacy. If yours is all wire, cloth can be spread over the top and 2 sides easily. The dog will run to a cage for protection if a child is too rough or when Play Time is over.
 

Electric Fence

      This is not my favorite method, but electronic fences are often effective if you don't wish to or can't construct a physical fence due to housing regulations within a development. But be careful not to use the shock collars during thunderstorms! In addition, make sure the fence is set up by a professional who knows the proper voltage to use for the size of your dog.  These can be very dangerous if not used properly. 
      Some dogs learn that the shock is momentary and the fence becomes ineffective , therefore it is important to begin training your dog how to use this device from the beginning.  This may help alleviate problems.  . Multiple shock probes added to electric collars can burn your dog if it is raining.  

 Our Recommendation:
       A wooden privacy fence prevents other animals from getting in, and your animals from getting out. This is the very best solution to unfettered exercise in a protected area. Dog runs can expose your dog to being attacked by another animal, with no chance to escape, not to mention minimal exercise.  A fence also helps contain pesticides that neighbors might spray on their lawn and gardens, as well as keeping delicious trash from blowing into your yard. A good fence is a worthwhile investment on many levels. You'll have piece of mind, a cleaner backyard, and a safer place to live.
