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.


Obesity is a common problem in dogs, but you can help your pet lose weight. Identifying the causes and following a total weight-management program can result in controlled weight loss and maintenance. A total weight-management program includes evaluating the animal, educating the pet owner, modifying behaviors, and tailoring the program to individual situations.
Obesity is defined as an increase in body weight, beyond the limitation of skeletal and physical requirements, resulting from an accumulation of excess body fat.
Obesity is caused when caloric intake exceeds caloric expenditure. This simply means that a dog eats more energy (calories) than it uses and stores the excess energy as fat.
There are many factors that can contribute to obesity:
Fat
Fiber and Fatty Acids
Carbohydrates and Special Ingredients
In addition, a diet that contains L-carnitine can help dogs metabolize fat. L-carnitine is a vitamin-like compound that helps burn fat.
A total weight-management program can lead to successful weight reduction in the obese dog. Complete evaluation by the veterinarian is always recommended, and owner compliance is essential to success.
IAMS™ and professional veterinary products provide optimum nutrition for animals that can benefit from a weight-management program.
