Took a walk in the park this afternnon and met 2 beautiful Great Danes, and their owner. Rocky is 9 years old, 192 lbs, and has cancer, though you couldn't tell by his playfulness. Samson is about 9 months old, 120 lbs and is rambunctious. They are gentle, but huge. Rocky came to my waist, Sammy only slightly smaller. '40' pounds of food a week!
