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 use a range of sounds to communicate with us and each other. Just as important is the body language they use to tell us how they feel or what they need. How well do you know your pooch’s unspoken cues? Read on to find out.
Dogs often stare at their owners because they love them. They want to make sure you’re okay or find clues for what you’ll do next — like making sure you’re not going for a car ride without them.
We love it when dogs do this, too, which has led to this trait being even more prominent.

Humans love that dogs look up at them in admiration, intense loyalty. One frequent observation researchers have made is that people who handle wild dogs ... they don't look their handlers in the eye like domesticated dogs do.”
Dogs have great hearing. High-frequency sounds that humans can’t hear are especially interesting to them. Head-tilting helps them track down the source. Owners find these head tilts super cute and often reward this behavior, which, of course, makes them do it more.
Dogs yawn when they’re tired, but it’s also a possible sign they’re stressed, impatient or frustrated — like when they’re in the vet’s office, or when you won’t throw that ball you’re holding already!
In a recent IAMS poll,* 90% of dog owners said their pet sits or lays on their feet and 100% of dogs said they love their owners. Dogs are very social creatures and this is a way for them to connect and be close to you. Plus, it keeps your feet warm.
Often called “raised hackles,” dogs do this when they’re nervous, threatened or showing aggression. It’s an adaptation from their wild days of attempting to make themselves look bigger.

You’re at risk of misinterpreting what the dog is trying to say to you. Context is everything.”
So be sure to pay attention to what your dog isn’t saying to keep them healthy and happy. Serving them
