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.
For most pet parents, the expense, time, and expertise involved in breeding dogs responsibly is beyond their reach. Here are some advantages to having your puppy spayed or neutered:
When to Spay or Neuter
Dogs should be spayed or neutered by the time they are 6 months old to avoid many dog health issues. Both operations are performed under anesthesia and may require an overnight stay at the veterinarian's office. Recovery time is quick, with most dogs resuming normal activity in a few days. Spaying (for females) consists of an ovario-hysterectomy.
Neutering involves the removal of the testicles. When you bring your puppy to the veterinarian's office for his first thorough examination, have the doctor explain the operation in detail and set up a time to have the procedure done.
