What is the best dog food for my English Mastiff puppy?

Meghan: What is the best food to feed my English Mastiff puppy?
I have been doing a lot of research on what to feed my english mastiff puppy. I am hoping for suggestions from others with mastiffs or giant breeds. I want to feed him a really good quality food at a somewhat reasonable price. Also, I have heard that they only need puppy food until they are 4 months, is this true? I would really appreciate some advice on this issue! Thanks!

My two mastiffs lived to be ten-years old. They were on Purina One. I also have two ancient cats–20 and 18-years old. People are always knocking Purina, but my pets have done very well on it.

Answer by luv big dogs
I have always been told (by vets, breeders, etc.) that giant breeds should never have puppy food. It doesn't meet the nutritional needs of giant breed puppies. My Mastiff female is currently 6 months and 80 lbs, so she is right on track for the breed. She was started on Nature's Recipe Adult Lamb & Rice, because that's what I was feeding my other dog. However, it made her very gassy, which didn't seem to bother her but wasn't all too pleasant for me!

They are now both on Purina Pro Plan Adult Lamb & Rice. Gas has been reduced by about 90%, stool is firm, and I have not had any problems with either dog. I know that it is not Solid Gold, King, Royal Canin, or any of the many 'top-quality' foods that you will hear recommended, but it is fairly easy to find, reasonably priced, and seems to work well for my dogs.

Mind you, I would never feed Purina Dog Chow, but the Pro Plan seems to have comparable ingredients to Nutro, Nature's Recipe, and many other higher quality foods.
Good luck!

Giant breeds have different needs than large breeds. Our vet and breeder both said do NOT feed puppy food (ever). Mastiffs need to grow really slow and keep their protein levels low while a puppy. Puppy food (even high quality) has way too much protein for mastiffs.

In all honesty, any "reasonably" priced food is not a high enough quality for them. Iams, Science diet, etc has too many fillers.
We buy a brand of food only available at small pet stores that specialize in nutrition. It costs about $ 50 for a 30 lb bag and lasts us about 3 weeks.
It seems "over the top" to many but you get what you pay for. I have seen people cut corners on nutrition with their mastiffs and they tend to have more health problems down the road.

My Sorcerer died in hosp in operation for bloat. Stomach too much dead to bring out of anesthetic.
I killed him 8yrs old. A few weeks before he had bloat, I took to doctor, he threw up in truck doc said alright now heart, lungs, color, stomach position alright. Doc said feed sm feedings of dry.

I feed him blue seal lamb & rice no soybean in it. At pm I feed a boiled supper, pasta chicken spinage, or well boiled veg on side. I had my warning first bloat. NEVER SHOULD HAVE GIVEN HIM DRY FOOD AGAIN,

AT LEAST I should have pre soaked until fully swollen and then taken measure.
Really should have made pasta and chicken for him for breakfast to, had my warning; I KILLED MY SORCERER.

    My Research is complete;; my Sorcerer, English Mastiff,

    in checking his records was 11 yrs.

    Dog bloat and its causes, is a medical unknown.

    After decades of experiments with Lab. Dogs, not one case of ‘bloat’ could be induced; doing everything Doctors believed would be wrong.

    So I am redeemed. I feed all my dogs the same, good fresh human food and treats.

    I believe we have learned many things about dog health.

    Intuitively we know all mammals need diverse foods, what they would get in a natural diet and ‘fresh’ as in a natural diet.

    Breeders will have much advice for you, ignore it.

    Follow what you observe in life.

    Breeders are still holding to the old tale of neutering preventing many type of cancer in dogs. WRONG, current research shows neutering leads to increased cancer incidents in dogs.

    Over vaccination for dogs has compromised immune systems and led to many immune diseases.

    Just as the Menopause treatment of human females with ‘’pregnant mare urine’’, has shown after 60 years, to cause all the diseases it was said to prevent.

    We as individuals are faced with making researched choices, our own research, in matters of medical intervention of ourselves and our dogs.
