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.


Oral care is a key component of your pet’s overall health: A smart regimen can help prevent the development of serious conditions. Keeping your pet’s teeth clean and bacteria-free results in more than just healthy teeth and fresh breath. With a little know-how and effort, you can protect your pet for a lifetime of companionship.
Tartar and gingivitis are the most common problems seen by veterinarians. The majority of dogs will develop these problems. Unchecked, these can lead to periodontitis and serious health concerns for your pet, up to and including, tooth loss and serious illness. But you can take action to control this and promote good oral health by incorporating the 3Ds: Daily Brushing, Dentistry. and Diet.
Daily brushing of your pet’s teeth will remove plaque and slow the development of tartar. When first beginning to brush, be gradual and make it a pleasant experience. Start by using your finger. Later, introduce a toothbrush. Be sure to praise and reassure your pet while brushing. Also, reward your pet afterward with play or a walk.
Talk with your veterinarian about annual or semiannual teeth cleaning—a dental prophylaxis or prophy for short. Teeth cleaning, performed by your veterinarian, is the only way to remove tartar.
Diet is important to good oral health. The mechanical, brushing action of dry, crunchy kibbles helps remove plaque and works to scrub teeth clean. Some diets also might include ingredients such as hexametaphosphate (HMP) that can help block tartar formation. Diet, daily brushing, and dentistry helps break the plaque-to- tartar cycle and optimize oral health.
