I have both of mine Chipped, with no health problems.

But, one needs to be aware...
There are about six Manufacturers of those Electronic ID Chips.
They operate/are activated by different Radio Frequencies (scanner).
Some Scanners will "read" more than one of the above Frequencies.
But, I'm unaware of any Scanner, that will read all the Frequencies used.

SO...
1) You should be aware of who Manufactured the Chip
(not Banfield for instance, but the actual Manufacturer)
2) Exactly what Frequency in KHz/MHz the Chip is activated with.
3) The Digital Number transmitted to the Scanner (individual to each Chip).

Needless to say, you should have the above information recorded for
each of your animals, in case of Lost/Stolen or other need to provide
proof of ownership.
