My Danes do free feed, which you will read is “forbidden” however, all my Danes have always been free fed and never had issues. I asked Dr. Jackson about it and he said that all my Danes look very healthy and so free feeding them is not an issue. But of course, please do what your Vet advises you to do. If your vet recommends elevated bowls, I have found the cheapest way to do that is by purchasing plant stands. I used to use just Dollar Store plastic bowls but they are so light that the dogs knock everything down. I know there is controversy on feeding on an elevated platform so please do as your vet recommends.
So go to some resale store and get really heavy cooking pots.
In addition to following best practices in feeding, there is also a stomach tacking procedure that can be done. Please talk to your Vet about it.
One other note on feeding. Danes have sensitive stomachs. As puppies I have them at a 20-22% protein to control growth. If you give them anymore than 25%, they will get what is called Wobbler Syndrome (http://www.all-about-great-danes.com/feeding-great-danes.html).
Our RufusxPippa puppies have rapid growth. They do get growing pains! Because of that, we have them on the Kirkalnd in the dark green bag ONLY. But always talk to your Vet about it.
Before I talk about the other foods, we need to address the Cardiomyopathy issue. Please see the latest information here and what foods are causing heart problems.
I have done Taste of the Wild (Sierra Roasted Lamb), Diamond Naturals, etc, they are all good however, they are on the list of foods causing cardiomyopathy so I do not recommend them. I personally have not had issues with them in the past. As adults, mine have done really well on the dog food dry kibble found at Costco. Kirkland in the Green Bag is super cheap but another Dane breeder told me to try it because it is made in the same place with the same ingredients as some of the super high quality dog foods. So I tried it and they were right! My Danes love the Kirkland dog bones and their wet food too (green can) and never have tummy issues. If your dog or puppy is not tolerating the Kirkland, try the Natural Balance Limited Ingredient in the dark green bag. I highly recommend keeping them on it until or unless the FDA updates the list and the Natural Balance or Kirkland are listed as unsafe foods. If you are changing the food, please do a slow implementation. A tiny amount at first, mixed into the Natural Balance Limited Ingredient in the dark green bag , for about 3-4 days. Watch for any bowel changes. If everything is ok, a little more and so on. If you see any bowel changes, stop the new food and revert back to the Natural Balance Limited Ingredient in the dark green bag . I would not recommend trying a new food again for at least 2 weeks and then you can repeat the process.
Please remember, I am NOT a Vet or medical professional. These are only my opinions!
Other things to note:
There is now sugar-free peanut butter on the market. It contains erythritol which is deadly to animals. Please read the ingredient list of all peanut butters.
