What Is the Best Age to Microchip a Dog? Expert Veterinary Guidance
The best age to microchip a dog is around 8 weeks old, though puppies can be microchipped as early as 6 to 8 weeks. It's never too late—adult and senior dogs can also be safely microchipped.
What Is the Best Age to Microchip a Puppy?
The ideal time to microchip your puppy is around 8 weeks of age. Many veterinarians recommend microchipping during the first round of puppy vaccinations, which typically occurs between 6 and 8 weeks old. At this stage, the puppy is large enough for the microchip to be safely implanted under the skin between the shoulder blades, and the procedure is quick—similar to a routine vaccination.
Microchipping at this early age ensures your pet is permanently identified before they venture into new environments or begin socialization. It also aligns with many local ordinances that require dogs to be microchipped by a certain age. If your puppy is older than 8 weeks, it's never too late—microchipping is safe and effective at any age.
Our team at Veterinary Medical Center of Woodland Hills follows guidelines from the American Veterinary Medical Association to ensure the procedure is as comfortable as possible. We combine microchipping with a wellness exam to check your puppy's overall health and discuss a vaccination schedule.

Is Dog Microchipping Required by Law?
In many regions, microchipping is legally required for dogs. While laws vary by state and locality, some areas mandate microchipping by a certain age—often around 8 weeks or when the dog is first licensed. For example, in the UK, all dogs must be microchipped by 8 weeks old, and owners can face fines for non-compliance. In the United States, requirements differ; some states have enacted laws for mandatory microchipping, while others leave it to local ordinances.
At Veterinary Medical Center of Woodland Hills, we stay informed on current regulations to help you comply. Even if not legally required where you live, microchipping is strongly recommended by the AVMA as the most reliable way to reunite lost pets with their families. We can advise you on any local rules for Woodland Hills, Calabasas, Agoura Hills, or surrounding areas.
Is It Ever Too Late to Microchip a Dog?
Absolutely not. Microchipping is safe and effective for dogs of any age—from 8-week-old puppies to senior pets. Many owners worry that their older dog might be too fragile, but the procedure is minimally invasive and well-tolerated. In fact, microchipping an adult or senior dog can be life-saving if they ever get lost.
Our team has microchipped dogs well into their golden years, and the process is the same as for a puppy: a quick injection under the skin, no anesthesia required. If you've adopted an older dog without a microchip, or simply never got around to it, now is the perfect time. We recommend combining the microchip with a wellness exam to ensure your pet is healthy enough for the procedure—though in most cases, there are no age-related restrictions.

How Long Do Dog Microchips Last & How Do They Work?
A dog microchip is a tiny integrated circuit encased in biocompatible glass, about the size of a grain of rice. It doesn't have a battery—it's activated by a scanner that emits a low-frequency radio wave, which powers the chip to transmit a unique identification number. This number is linked to your contact information in a national registry.
Microchips are designed to last the lifetime of your pet. They have no moving parts and are not subject to wear and tear. Once implanted, the chip stays in place under the skin between the shoulder blades, though it can occasionally migrate slightly. That's why we recommend checking the chip's position during annual exams. If you ever move or change phone numbers, simply update your registry information to keep your pet's ID current.
Are There Any Disadvantages to Microchipping a Dog?
A good fit if…
- You want permanent ID: A microchip can't be lost, removed, or altered like a collar tag.
- Your dog travels internationally: Many countries require an ISO microchip for entry.
- You're prepared to register it: The chip is only useful if you keep your contact info up to date.
Consider another option if…
- You're concerned about migration: Rarely, chips move from the injection site; we can check placement during exams.
- Your dog has a known allergy: Adverse reactions are extremely rare, but discuss any concerns with your vet.
Overall, the benefits of microchipping far outweigh the minimal risks. If you have specific health concerns, our team can evaluate your dog and recommend the best approach.
Should You Microchip Your Dog Yourself or See a Vet?
A good fit if…
- You trust professional expertise: Veterinarians are trained to implant chips correctly, minimizing pain and migration risk.
- You want proper registration: We ensure the chip is scanned and registered before you leave.
- You value a full health check: Microchipping is often combined with a wellness exam.
Consider another option if…
- You're tempted by DIY kits: At-home microchipping carries risks of improper placement, infection, or failure to register.
- You're on a tight budget: Some low-cost clinics offer microchipping at reduced rates, but always ensure it's done by a qualified professional.
We strongly recommend having a veterinarian implant the microchip. It's quick, safe, and gives you peace of mind that the chip is correctly placed and registered. For more details, see our page on where to get a dog scanned for a microchip.
Frequently asked questions

Two potential disadvantages are microchip migration (the chip moves from its original spot) and rare cases of infection at the injection site. Both are uncommon and can be minimized by having a trained veterinarian perform the procedure.
What states prohibit microchipping?
No U.S. states prohibit microchipping pets. Some states have laws requiring microchipping for certain animals, but none ban the practice. Always check local regulations, as ordinances can vary by city or county.

Can a cell phone scan a pet microchip?
