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.
Congratulations! You're the proud owner of a puppy. It's important to take steps now to ensure great puppy health. Louise Murray, DVM, director of the ASPCA's Bergh Memorial Animal Hospital in New York City and author of Vet Confidential (Ballantine, 2008), offers these pointers for your puppy's first year.
Talk to friends to find a veterinarian you can trust. Within a week of bringing your puppy home, take him for a checkup. The doctor will perform a physical and start keeping a detailed medical history.
The overvaccination of pets is currently a hot topic, Murray says. The question is, however, not whether to vaccinate but which vaccines to use and how often. What she calls the 'core vaccines'—those for parvovirus, distemper, adenovirus type 2, and rabies—are essential. 'These shots protect your dog from diseases that are very real, very common, and very dangerous,' she says. Additional vaccines may be necessary based on where you live, where you take your dog, and whether you travel.
Choose a reputable brand of dog food and discuss your choice with your veterinarian. In his first year, your puppy will be on food that is specifically geared toward younger dogs and will likely eat three times a day rather than once or twice.
An excellent measure against pet overpopulation, this procedure ideally should be performed between ages 4 and 5 months, which is before a female dog goes into her first heat and before a male enters puberty. A female dog who is spayed before going into heat is 2,000 times less likely to get breast cancer, Murray says. Males who are neutered before entering puberty have fewer behavioral issues, such as aggression toward other dogs and urine marking.
Puppy Health: Flea, Tick, and Heartworm Medicines
Most dogs should be on medicine year-round to prevent heartworm, a life-threatening parasitic infestation, Murray says. Fleas, often seen as just an annoyance, can actually cause severe skin problems and even anemia. Ticks carry multiple diseases (including Lyme disease and Rocky Mountain Spotted Fever). Your veterinarian can prescribe effective preventives for these two problems.
