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.


You’ve likely heard your dog let loose his inner wolf and belt out a few long howls. 73% of dog owners in a recent IAMS poll* believe they do this to communicate. This form of vocalization has a long history and is used for different reasons. Understanding more about howling will help you understand your pooch better.
Howling is an ancient trait wolves use to communicate with other members of their pack and other packs over long distances. They may be trying to locate a lost member, show off the size of their pack or warn of danger. It’s like a canine group text.
A wolf’s howl can be heard up to 10 miles away.
Each wolf has their own unique howl, so pack members know who they are, even miles apart.
Dogs instinctually respond to howling-like noises by howling themselves. Sounds such as sirens, other dogs, singing or your kid learning the violin is usually enough to get them to sound off.
Dogs are still very social animals; it’s just that now we’re their pack. When they miss us, they’ll howl in hopes we respond.
Opens a new windowDr. James Serpell, BSc, PhD, Professor of Humane Ethics & Animal Welfare at University of Pennsylvania School of Veterinary Medicine, explains it this way: “That [howling] is an attempt on the part of the dog to ask the owner basically, ‘Where are you so that I can rejoin you?’”
Dr. James Serpell doesn’t believe so. “My own research has shown that it is common across breeds. People think huskies may be more prone to group howling.”
Dogs going through separation anxiety may howl excessively when left home alone. Dr. Jo Gale, BVetMed CertLAS MRCVS, Senior Manager for Global Science Advocacy at Waltham Petcare Science Institute, says, “If you reinforce quiet behavior, they are less likely to continue howling.” You can do this by quieting your dog and then leaving for a very brief time before returning and rewarding them when they stay quiet. Gradually increase the time you’re gone to reassure them you’ll always be back.
