Microchipping

Collars and ID tags are valuable, but they can slip off, break, or fade. A microchip cannot be removed by accident, cannot be lost with a collar, and does not wear out. It is recommended for every dog and cat because:

• Lost pets are often found far from home, where no one knows the owner's phone number
• Shelters and animal control officers scan every incoming animal as standard practice
• The Southern California Calabasas area includes mountain terrain, busy roads, and wildlife corridors — environments where a dog can travel considerable distance quickly
• Even indoor cats escape; without a chip, identification depends entirely on the collar remaining on

The American Veterinary Medical Association (AVMA) and every major shelter organization recommend microchipping as a basic standard of care for all pets.

Microchipping is a brief, straightforward procedure that does not require anesthesia in most pets:

• The chip arrives pre-loaded in a sterile, single-use needle (similar in gauge to a vaccination needle but slightly larger)
• The skin over the scruff — between and just behind the shoulder blades — is tented, and the chip is injected in one smooth motion
• The needle is withdrawn and light pressure is applied for a few seconds; no sutures are needed
• The chip is immediately scanned with a universal reader to verify the number reads correctly
• The chip number is registered in a national database (such as HomeAgain, AKC Reunite, or Found Animals) linked to the owner's current contact information

The entire process takes about 15 to 30 seconds. The chip does not move significantly once implanted — the surrounding tissue anchors it in place within a few weeks.

Most dogs and cats feel only a brief pinch during implantation and return immediately to their normal behavior. Some pets are more sensitive to the injection than others, but the discomfort is transient and comparable to a routine vaccine. No bandaging, stitches, or recovery time is needed. A small, firm nodule may occasionally be palpable at the site for a short period — this is normal inflammation from the needle and resolves on its own. Rarely, chips can migrate slightly from the original implant site; annual scanning at wellness visits confirms the chip is still readable.

Microchips have been used in companion animals for more than 30 years, with hundreds of millions of animals chipped worldwide. The chip itself is biologically inert (encased in biocompatible glass) and triggers no immune reaction in the vast majority of pets. Reports of chip-site tumors exist in the scientific literature, but are extremely rare — the benefit of microchipping in reuniting lost pets far outweighs this theoretical risk. Chips do not emit signals at rest, produce no heat, and have no known interaction with common medical equipment. After implantation, the single most important step is keeping the registry contact information up to date — a chip linked to an old phone number cannot help reunite a lost pet.
