the  best  dogs i  have  been  around  are  Golden  Retrievers and Huskys,I  love  a  husky,but  they like  to  hunt  to  much  and roam,a friend  of  mine  had one  and  I  had  a  husky  half  breed,excellent  dogs,but  they  would drag in dead ground  hogs  and  uuuh  an  occasional goat,when  they were together and mine  ran  a  Mercedes  into  a tree,why  the driver  choose that over  running  over  the  dog I  have  no Idea,needless  to  say ole Kayak  got  put  on a short  chain after  that
and he  was bad  to  drill  the  neighbors dog   in  the butt,when he  would  get inside  the chain,with  all  the  neighbors kids  screaming and  crying,what  fun he  was  lol
I  did  get  him into  an electric  fence after all  that,he  was  the  best dog I ever  had though 
I've  been around  some exceptionally  smart Golden Retrievers ,my  friend  had one  that knew  how  to lift  the  latch  on his  his  gate  and  would  go  and steal  a cucumber  from  the side  of  the garden,he knew  not  to walk in the garden  and  then  would  run  back inside  his  fence and  then set  the latch  back in place,  and  you  could  say truck or  van  and  he would  go to the right  vehicle  
  another  friend  had  a  ***** Golden and she  figured  out  how  to flip Frisbee's around  till  she  could  fit  5 in her mouth  and  bring  em  back  to you and would  be ready to go again,she was relentless  in her  pursuit  of Frisbee's,she  did bring  back a lot  of extra Frisbee's  though  
 
  
of  course  that is  just working  with  a dog,get one  that suites what  you  want and  how  active you  want  them  to be,gotta watch out  for  the hound  dogs,they  love  to be on the hunt and  you never  know  what  they will be  hunting 
another  friends  of  mines  Husky  went  and  killed  a bunch  of fighting cocks  and  that cost  him around  1500  bucks  for  that chicken  dinner
