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.


 
 How much do you know about the food you’re buying for your puppy? When shopping for puppy food, pay attention to these three sections of a dog food label.
This section lists all the ingredients that make up the product. The ingredients are listed in descending order according to weight before cooking. In dry food, look for a source of high-quality animal-based protein: chicken or lamb, for example. Dogs thrive on animal proteins.
 
Manufacturers who use large amounts of vegetable proteins might be saving money by providing basic — but not optimal — nutrition. You should also avoid artificial colors and flavors, which offer no nutritional benefits.
Near the ingredient panel should be a chart of percentages called the 'guaranteed analysis.' These figures reveal the basic nutrient makeup of the dog food's formula and protein content. The minimum percentages of protein and fat and the maximum percentages of fiber and moisture (water) should be listed.
This information must be included on the label by law. A toll-free number or web address for the manufacturer may also be listed. Manufacturers who list a phone number, such as IAMS™, generally have a high-quality product and welcome consumer calls and questions. If you would like information about IAMS products, visit our website or call us toll-free at 800-525-4267.
