A little knowledge for those who care to read it posted by Amelie Morgan thank you very much as well as thank you to Erin Elizabeth Gossman for your input, as well and the rest of the people who took their time to answer my question.

OK here are my observations on this. Raising a bowl for a puppy will not significantly alter their structure. Let's say a pup eats 3 times a day, 10 minutes each meal, that is 30 minutes standing in this position. What about the other 23.5 HOURS ... a day? Is it better for them for other reasons? Maybe. Maybe not. Large breeds like Danes *might benefit from raised bowls when fed kibble.
Here is what it boils down to-genetics. Also WHAT you feed. If one feeds a food too high in calories to a large breed pup, the bones and tendons have a hard time keeping up with the growth of fat and muscle, thus causing the tendons to stretch. We see this as dogs down in the pasturns, splayed toes, flat hocks etc. Undernutrition can be just as bad, causing ricketts, the most common causes are dietary insufficiencies of phosphorus or vitamin D. mother of the bride dresses for beach wedding
My dogs always eat off the ground, ripping, tearing, pulling. Of course this is whole prey or large frozen chunks. That right there will help build muscle, tighten tendons (if it's in their genetic make up to have tight ligiments and tendons)
Think about a dog eating real food, they brace their front legs on it, grasp it with mouth, pull. The back, thighs, legs etc all get a workout.
Honestly it is up to you if you want to buy raised bowls. Truthfully though I feel they are not needed.
