What to feed my mastiff? You need to make sure you discuss this with your vet. Some of the best foods available don't work as with with this breed as it goes right through them and they don't put on weight. But you definitely don't want to skimp based on budget.

Your dog will look good if its on the right diet and stools will be firm. Cowpies are not fun to clean up after.

There are many opinions on and what to feed your mastiff, how long to feed puppy food for, and large breed or regular food... If you have specific questions, feel free to email, but I don't like to name specific brands on this site.
