Mine is big enough, that I can't stand flat footed straddling her at the shoulders (I'm 6'3"). Took her to Petsmart and weighed her for the first time in a long time. And she is a svelte and petite, 205 pounds... 5 year old English Mastiff... She was a hit at Petsmart, and she loves to ride in the back of my Grand Cherokee.
Just a great big lovable fuzzball...
