WE PURCHASED OUR FOUNDATION MALE 'ESCOBAR' IN 2007 AND HE WEIGHED 82.7 LBS. ON A VET SCALE. HE WAS IN EXCELLENT HEALTH BUT WE WANTED TO MAXIMIZE HIS GROWTH POTENTIAL FOR THE MASSIVE SIZE OF HIS FRAME. WE IMMEDIATELY STARTED HIM ON NUVET VITAMINS AND AS OF SPRING 2008 HE WEIGHED 100.4 LBS. ON A VET SCALE. HE'S STILL EXTREMELY HEALTHY AND WITH REGULAR EXERCISE HE HAS GAINED MUSCLE TONE SINCE HE'S BEEN ON THE VITAMINS. HE HAS TONS OF ENERGY FOR HIS SIZE AND HIS COAT STAYS SHINY AND IN PERFECT CONDITION ALL YEAR AROUND. NUVET WORKS BEST ON PREGNANT AND NURSING FEMALES, AND WE HIGHLY RECOMMEND THE VITAMINS FOR FEMALES ON A DAILY BASIS. ALL OUR FEMALES BOUNCE BACK FROM THEIR PREGNANCIES WITHIN A MONTH FROM HAVING PUPS AND RARELY BLOW THEIR COAT. OUR FOUNDATION FEMALE 'ANGEL' RECENTLY WON 1ST PLACE IN HER ABKC CLASS LESS THAN 8 WEEKS AFTER HAVING PUPS! FROM OUR EXPERIENCE THE VITAMINS WORK WONDERS ON HELPING FEMALES RECOVER FROM THE STRESS OF A PREGNANCY. ALL PUPPIES PURCHASED FROM OUR KENNEL COME WITH A SAMPLE OF NUVET VITAMINS.
