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.


Worried that your small-breed dog is packing on the pounds? Run your hands along his backbone. You should be able to feel (but not see) his ribs. You also should see a clearly defined waist behind the ribs. If you can’t, follow these seven tips from Debra Eldredge, a veterinarian and co-author of “Dog Owner's Home Veterinary Handbook,” published by Howell Book House.
Before you put your overweight dog on a diet, schedule an appointment with the vet to make sure an underlying health problem isn’t causing the numbers on the scale to creep up.
Snacks and table scraps might account for your overweight dog’s bulging belly, Eldredge says. If curtailing in-between meals doesn’t make a difference, consider continuing with the same amount of food but switching to a different formula. Your vet can give you guidance.
Thawed frozen green beans, canned pumpkin (which is fiber-rich and filling) and cut-up carrots make satisfying, low-calorie snacks for your pet.
A study showed that dogs can count up to six or seven, Eldredge says. If he is accustomed to getting two small biscuits as a treat, break one biscuit into two pieces. By his count, he’s still getting two treats!
As much as your overweight dog loves treats, he also loves taking walks, playing and spending time with you. You also can replace biscuits with a couple of pieces of the kibble he would get during mealtime.
Is your bichon staring up at you with those beautiful eyes as you nibble on peanuts? He’s probably not hungry. As you have your snack, offer him a piece of kibble. If he turns it down, he’s not really hungry — he just wants your peanuts!
If your overweight dog has just a couple of pounds to lose, it can be hard to gauge whether he is making progress. Ask your clinic if it’s OK if you stop in once a week so he can step onto the doctor’s scale.
