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.


 
 Traditionally, owners of large-breed and mature/senior dogs have known that their dogs may be predisposed to common joint and skeletal conditions—problems that may affect their mobility and overall wellness. The good news is that specially formulated diets and dog care products can help promote skeletal and joint health and assist in maintaining healthy cartilage.
Including specific nutrients in your dog's diet can help maintain healthy joints. Optimal levels of vitamins and minerals are found in IAMS™ dog care products and promote the efficient production of cartilage.
IAMS has formulas that are lower in fat and calories compared with our other adult maintenance formulas. Bones are the framework of the body, and the more weight added to the frame, the more stress joints experience. IAMS formulas such as IAMS™ ProActive Health™ Mature Adult are designed to help keep large-breed or mature dogs at an optimal weight to minimize joint stress.
