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.


Dogs are creatures of habit and can resist change when trying to switch their diets. It's important to completely stop feeding from the table. This is best accomplished by removing the pet from the kitchen during mealtimes. Be persistent when offering dry food. The pet may refuse to eat for several meals before deciding to give the food a try. Heating food in the microwave increases the aroma of the food and will often entice a pet to eat. Another alternative is to try mixing some wet food with the dry food, or topping it with a sauce or gravy specifically formulated for pets. Be assured that the pet eats to meet an energy need and will eventually begin to eat unless there is an underlying medical issue.
Keep in mind that the pet's stool should be small and firm. Most cases of constipation are temporary and due to dietary interruptions. Loose stools also are often temporary and can be due to dietary interruptions, as well as many other things, including an abrupt change in diet, overeating, parasites, medication, eating table scraps, viral or bacterial infections, and stress. If constipation or diarrhea persists, however, it is important to consult a veterinarian.
No. Dead grass is caused by a heavy concentration of urine—usually when a dog urinates in the same spot over and over. Try to train the dog to go to a designated, inconspicuous area of the yard. If this is impossible, try to hose the area as quickly as possible to dilute the urine. Sometimes the discoloration is due to acidic ground pH, which can usually be remedied with a lime treatment.
