pedigree or not / Is training the best for JR

Question
I have just welcomed into my home a jack russell terrier I want to know why they are classed as a none pedigree why is this?. Is it a good idea to take her to puppy classes  

Answer
HI JACKIE
I WOULD DEFINATELY JOIN INTO A GOOD OBEDIENCE CLASS OR KINDERGARTEN CLASS TO BEGIN WITH.
THIS BREED IS MOST HIPER AND IF NOT TRAINED IMMEDIATELY AND WORKED WITH DAILY IT CAN CHEW YOUR HOUSE APART.  THEY REQUIRE ALOT OF EXERCISE AND LIKE TO DO THINGS.  THEY ARE THE CRAWLERS OF UNDERGROUND TUNNELS?
I HAVE NEVER HEARD OF THEM BEING A NON PEDIGREE DOG OR BREED?  MAYBE NOT ENOUGH LINES ON THEM TO MAKE A GOOD PEDIGREE?  I TRULY MUST INVESTIGATE THIS FOR I NEVER HEARD OF IT.  IF THERE ARE NOT ENOUGH PEDIGREE LINES IN BREEDING THEM THEN THAT WOULD BE ONE REASON.  IN OTHER WORDS INBREEDING MAYBE???  I WILL CHECK.
