The timeline for feeding your new puppy changes rapidly over the first six months. Learn what and how you should feed your puppy based on the key development milestones she will experience.
Due to breed differences and animal individuality, it is impossible to predict exact dates for a puppy’s growth and development milestones. However, by using the following milestones as a guide for healthy growth, developmental problems can be spotted — and possibly prevented — early on. By knowing these milestones, you’ll also know when your puppy is ready to begin weaning.
| Age | Milestone |
|---|---|
| 7-10 days old | Puppies double their birth weight. Puppies begin to urinate and defecate on their own. |
| 10-18 days old | Puppies attempt to stand. Puppies’ eyes begin to open. Puppies’ ears begin to open. |
| 18-21 days old | Puppies hear and respond to noises. Puppies begin to walk. |
| 3 weeks old | Begin weaning process for orphaned puppies. Puppies begin responsive vocalization. Deciduous (baby) teeth will begin erupting. |
| 4 weeks old | Begin weaning process for mother-fed puppies. |
| 3–6 months old | Puppies’ adult teeth erupt. |
When your puppy is ready to begin weaning (at around 4 weeks for mother-fed puppies and 3 weeks for orphaned puppies), use this step-by-step process:
The entire process should take approximately three weeks.


Providing your dog with a balanced diet of nutritious dog food will ensure they get adequate amounts of protein, fat and fiber. All three are essential to your dog’s health and happiness — and all three can be found in every IAMS™ product we produce. Learn more about how these three vital elements can support your dog’s whole-body health.

Protein Protein helps keep your dog’s muscles strong.
Protein helps keep your dog’s muscles strong. It also provides the amino acids necessary to build and repair proteins in their body. Many of these amino acids must be acquired through a dog’s diet.
Recipes contain animal-based proteins that provide the essential amino acids dogs need. Plus, we conduct special refining and quality assurance tests to ensure we only use high-quality, highly digestible protein sources for increased digestibility.

Fat gives your dog energy and helps nourish their skin and coat.
Fat provides energy. Your dog needs two types of fatty acids: omega-6 andomega-3 fatty acids. Omega-6 fatty acids are found in chicken fat and corn.Omega-3 fatty acids are found in ingredients such as canola, fish meal or oil, andflax. Both types help nourish and support your dog’s skin and coat.
Fiber and prebiotics help support your dog’s digestion.
IAMS™ dog food recipes feature a tailored blend of natural fiber from ingredients like beet pulp, as well as prebiotics to help support your dog’s digestion. Research has shown that moderately fermentable fiber, such as beet pulp, enhances intestinal health.
Feeding your dog a balanced diet that contains the right amounts of protein, fats and fiber is one of the most important ways you can care for and nourish them. To see the di!erence a healthy diet can make in your dog, feed them an IAMS recipe that’s tailored to their unique dietary needs, such as their size, age and breed. Are you ready to See the Wow?
