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.


Whether your dog is a big sweetie, a big weirdo or a big athlete, here’s what you need to know about taking care of your big dog.
First, all big dogs start out as little dogs. But pretty soon they grow up — and so does their appetite, their toys, their dog bowls, the vet bill and their need for speed.
He started to grow. And pretty soon he was bigger than the recliner.
Sometimes it can take more than two years for them to reach their full size.
And you won’t like to think about it too much, but their life spans are shorter, too: about 10 to 12 years.
No wonder you'll let him push you off the bed at night.
If a large dog gets too much food as a pup, they’re at a higher risk of growing too quickly, which can cause joint trouble.
For large breeds, being overweight is especially problematic. All that extra weight can be a lot for the joints to carry around.
Keep your good old dog healthy by practicing portion control and feeding nutritious food like IAMS™ Mature Adult Large Breed.
How will she catch a screaming 15-mile-an-hour Frisbee in midair if she has knee trouble.
Back in the day, large-breed dogs were especially energetic. They were working dogs, herders, hunters, cart pullers and people protectors.
Who are we to deny their evolution?
Make sure your dog gets exercise every day.
How do you accomplish this? Walk, walk and more walk. And add in some running, jumping, chasing, hiking, fetching, dog-park visiting, swimming and even agility courses.
Repeat this mantra:
'I am the alpha.'
When it comes to training, think of it this way: The bigger the dog, the harder it is to hide behavior problems. And if you can’t control your super-sized soulmate, they could inadvertently cause damage or hurt someone.
Living large is all about biting the wind and living that sweet, sweet life.
