HELP, hi we have a jack russell. SHE IS 8 YEARS OLD. WE HAVE HAD HER SINCE SHE WAS A PUPPY. WE GOT THROUGH THE DESTRUCTION OF CHEWING, ETC. SHE HAS ALWAYS BEEN A HYPER, ANXIETY RIDDEN, DOG. SHE IS LSO EXTREMLY UNFRIENDLY TOWARDS OTHER ANIMALS ( WILL KILL ). SO WE ARE EVER CAUTIOUS AND RESPONSIBLE REGARDING THIS. I HAVE HAD MANY DOGS IN MY LIFE TIME, AND THEY HAVE ALL HAD THE SAME ENVIRONMENT, AND THIS IS THE ONLY DOG I HAVE EVER HAD WHO IS LIKE THIS. SHE WAS BORN LIKE THIS. WE ARE VERY PATIENT PEOPLW WITH NO CHILDREN SO WE WORK WITH IT. HOWEVER MY CONCERN IS THAT AS SHE GETS OLDER SHE IS MORE AND MORE ANXIETY RIDDEN. ITS NOT SEPERATION ANXIETY, IT IS A CONSTANT LOW GRADE ANXIETY AND IT GOES INTO OVERDRIVE WITH ANY NOISE, BBQ LID FALLING, LOUD VOICE OUTSIDE, THUNDER, SOFT RAIN ( BECAUSE SHE THEN ANTICIPATES THUNDER!!!) SMART DOG. SO FINALLY BECAUSE NOTHING WORKS8 tried every reccommendation on earth)WE LISTENNED TO THE VET AND TRIED PROZAC ( MADE HER WORSE!!) TOOK HER OFF IT. ANY SUGGESTIONS> SHE WILL SHAKE FOR HOURS AFTER HEARING A LOUD NOISE, PLEASE HELP

Answer
Hello  this is a sound sensitive dog. The best thing you can do is limit loud scary noises/droped pans clanged dishes loud music/tv slamming dog yelling. You must never yell at this dog or smack her or she will become ever more worse. I can also reccomend comforting her when she is frightened...reasureing her its ok will help calm her.
