What does your 3-month-old Puppy need for nutrition to grow healthier and stronger?

Think of your puppy as a fast-growing toddler, except one who grows at nearly 20 times the speed. That’s why Puppy nutrition needs to be dense, balanced, and thoughtfully chosen.

• High-quality proteins (for muscle development)
• Healthy fats (for energy and brain development)
• Essential vitamins & minerals (for bones, immunity, digestion)
• DHA (for sharper learning, yes, it really helps their “training brain”)
• Calcium & phosphorus (for skeletal strength)

How Much Should a 3-Month-Old Puppy Eat?

Overfeeding and underfeeding are two common mistakes new parents unintentionally make. A 3-month-old puppy needs multiple small meals because their digestive system isn’t mature enough for large portions.

Most puppies at this age thrive on three structured meals a day. However, quantity depends heavily on breed size, metabolism, and activity level.

A general rule of the Puppy feeding guide is:

• Small breeds: ½ to 1 cup per day
• Medium breeds: 1 to 1.5 cups per day
• Large breeds: 1.5 to 2.5 cups per day

But portion control becomes much clearer when broken down breed-wise, which you will find in the tables below.

Types of Puppy Food (Pros and Cons)

Dry puppy food is the most convenient, economical, and great for dental health. Puppies also enjoy the crunch as their teeth develop, and it blends wonderfully with warm water or a splash of goat milk for softer texture days.

Some dog parents go for homemade puppy food because they feel that fresh is always better. Although home-cooked meals may seem very healthy and good, they are usually deprived of very important nutrients unless they are properly prepared with a vet’s guidance.

The best approach? A thoughtful mix, using dry food as the foundation, wet food for flavor, and small homemade additions if approved by your vet.
