Puppy Food for Mastiffs Buyer’s Guide

Choosing the right puppy food for your Mastiff is very important, as he has some specific nutritional requirements for optimal growth and development.  Mastiffs reach maturity between 18 and 24 months, which is much later than other puppies. A poor diet or excess fat in that time can lead to orthopedic diseases such as hip dysplasia.  So, a high-quality food that is high in protein, low in fat and rich in vitamins and minerals is essential for lean muscle growth over time.  This could mean a higher price tag for your Mastiff’s food, but it is well worth the cost to prevent health or weight issues down the road.

Our buying guide reviews the best puppy food for Mastiffs on the market so you can choose the right one for your dog.  The following are specific nutritional considerations that should be made and will help you choose which puppy food you need for your Mastiff.

Protein and Fat

Like most puppies, protein is especially important for the development of a strong muscular system and should make up at least 25 per cent of the blend.  Be sure to choose high-quality, lean protein sources such as chicken, lamb, wild game or fish.  A low-fat recipe will contain less than 25 per cent of calories from fat, so other meats may also be good choices, provided the recipe is well-balanced overall.  Real meat should be at least the first ingredient on the label, and contain as few fillers, preservatives or by-products as possible.

Calcium, Phosphorous and Vitamin D

Your Mastiff puppy’s diet needs to include adequate sources of calcium, phosphorous and vitamin D.  These provide the necessary building blocks for healthy bones and teeth.  Vitamin D will help prevent softening of the bones. Do not over-supplement, however, as too much calcium and Vitamin D can also be harmful.  Choose a puppy food specifically designed for large breeds for the right balance.

Other Nutritional Considerations

A puppy Mastiff will need the omega-3 fatty acid DHA.  This will support his brain development and eyesight and usually comes from a fish oil, such as Salmon.  It’s also important to choose the right caloric intake for your puppy – from about 3,200 to 4,100 kcal/kg.  Refer to the label on your Mastiff’s puppy food for its caloric information.  Too many calories can lead to dangerous weight gain, and over-supplementing with certain nutrients.  Finally, many Mastiffs are prone to allergies, so choose a blend free from corn, wheat or soy for good measure.
