too much stretching?

YOU HAVE THE RIGHT IDEA NANCY. THERE HAS ALWAYS BEEN CONTROVERSY ABOUT STRETCHING. TO SOLVE MY OWN QUESTION MANY YEARS AGO, I WATCHED THE ANIMALS. tHE DOG ALWAY STRETCHES WHEN HE IS LAYING DOWN FOR A TIME AND, STANDS UP. SO DO MANY OTHER ANIMALS. BUT, THEY DO NOT KEEP STRETCHING A CERTAIN AREA. AND, WHEN THEY RUN, THEY DO NOT STRETCH AFTERWARDS. THEY PLOP DOWN. JUST MY OWN LITTLE STUDY. GOOD LUCK BRIAN ROZZI.
