Need a good dog food for older Great Dane?

Maybe a grain free food such as Taste of the Wild would be good. It also has a pretty high protein content compared to some foods, but not as high as a few others.

Your Dane should already be on a good quality food that doesn't contain corn, wheat, soy, by products unnamed meat/fat sources, animal digest and the like..

Some good food choices for a Great Dane of any age:

Taste of the Wild (all formulas), Orijen, Acana, Canidae Pure Element, Merrick Before Grain, Back to Basics, Canidae ALS, Nature's Domain, Nayural Balance, Fromm Gold, Fromm 4 Star,Blue Basics,Evangers, Chicken Soup for the Dog Lover's Soul,Earthborn Primitive Natural Innova Prime Grain Free, just to name a few.

Stay far away from foods such as Science Diet, Purina, Pedigree, IAMS/Eukanuba, Royal Canin & the like.They contain a lot of grains that dogs don't need as well as by products and other undesirable things and they are very low on meat/meat meals.

RAW. Pure protein, calcium, and just AMAZING! Had an amazing transformation with my 2 dogs! No dog food is good for dogs. No offense to all of the kibble feeders. Kibble is known for causing ALL sorts of diseases. Here is a list of those diseases: Dermatitises of all sorts, cancers, joint problems, heart problems, kidney problems, digestive problems ("lack of enzymes"), liver problems, pancreas problems, coat problems, tooth problems, anal gland problems, glandular disorders, allergies, and soft doughy bodies. Yes, even kibble like Orijen and Acana cause these. The thing is, is that kibble is processed and has a whole bunch of added things to it that dogs don't need. Most kibbles add potatoes, peas, supplements, etc, that dogs DON'T need.

You see, dogs are CARNIVORES not OMNIVORES. If you dissected a dog, you would notice that its internal organs are almost IDENTICAL to the wolf's. Only 0.2% ISN'T the same. Dogs are not made for digesting vegetables. The enzymes in their mouths are specifically made for breaking down MEAT. Sure, they can eat veggies, but they're not designed to and often have a hard time digesting them.

Dogs need a COMPLETELY raw diet to be healthy. This would be 80% muscle meat, 10% organs, and 10% bone. These diets aren't even expensive if you can find the right sources. I get my meat from hunting, my hunting friends, my butcher shop, or I go to the store and see what's on sale. Meat is cheaper if you can get it RIGHT when it's about to expire. Dogs don't care if the meat is a little "ripe" and it certainly won't hurt them. I also post ads on craigslist about wanting FREE freezer-burnt or expired meat that no-one wants and that sometimes works too.

I just switched my Great Dane from Royal Canin Giant Breed to Innova Large Breed and he LOVES it. Granted he is a puppy but the brand overall has gotten good reviews from what I have read, and they also have a Senior Large Breed bag as well.

Check out the Science Diet and Blue brands, they do cost more than the regular brands but they do the job. I have three Labs
