The Pros

The advantages of inserting a microchip in your pet are numerous:

• As we have already said, the procedure is quick and causes no pain for your pet;
• It is highly effective in returning pets to their owners when they go missing;
• The presence of the microchip and the information contained on the chip register demonstrates who owns the pet in the event someone else takes your missing animal in and decides to give them a “new home”;
• Microchips are usually used for cats and dogs but they are also eminently suitable for a wide range of other pets and animals, including livestock;
• The chip reader information is always clear and will never fade unlike a tattoo;
• Chipping your pet is permanent unlike using a collar and tag; and
• Shelters and the police will automatically scan a found pet to see if the animal has a chip.

Chipping your pet dramatically increases the odds of being reunited with them if they go missing compared to traditional forms of finding a missing animal.

This is not to say that there aren’t any drawbacks to the micro-chipping your pet.

The Cons

• Some microchips are not readable by different types of chip reader, so even if your pet is chipped, unless the shelter is operating the appropriate type of reader, your pet’s microchip may not actually be detected and read;
• Microchips are not visible and there is nothing to say that a pet has been chipped unless there is an additional identifying tag on their collar, though collars and tags may be lost as well – this leads to the possibility that your pet may be “adopted” by the finder who may be blissfully unaware you own the pet;
• The owner must keep the register updated with their contact information and frequently there are costs involved in maintaining the entry and for making any changes to it;
• The chip can migrate within your pet’s body which may make it impossible to read with a scanner;
• Microchips are not GPS tracking devices, so they do not give the animal’s position if it goes missing though many people assume this is in fact the case;
• The technology is not widely known to the general public who may therefore not know that the pet should be scanned in the first place – this means it is essential to still tag your pet and also to make it clear that there is microchip inserted; and
• When a pet does go missing, owners with an animal which has been chipped tend to assume the pet will be returned to them because of this.  As a result, they neglect to take action to locate their pet themselves, such as calling the shelters and placing missing posters around the neighborhood.

Asset Tags by Maverick Label – Mark Trumper

More dogs and cats are lost in winter than at any other time of the year so it becomes doubly important that they are properly tagged and identifiable.  If your pet carries an identification tag, the chances of being reunited with your pet quadruple while inserting a microchip further increases the probability of Fido or Frisky making it back home after wandering off.

Microchipping involves the painless injection of a small microchip device usually under the skin of the scruff of the neck.  Once inserted, a scanner can be used to collect the information contained on the chip which will include the owners information as well as the pet’s name and any medical or behavioral issues.

Tagging or microchipping your pet may also be a legal requirement depending on where you live.  Some states require a tag and for those that do not, county or municipal bylaws may impose an obligation upon the owners.  In addition. indoor pets should also be tagged and/or microchipped; the reasoning that as the pet lives indoors they cannot get lost is fallcious and indeed, if an indoor pet does find themself in the great outdoors, there is a need to recover the pet that much sooner.

Whichever method you use for identification, you are relying on simple human behavior when it comes to getting your pet home; human nature being what it is, there is an automatic reaction to check the collar of a potential stray and agencies who come across a stray will automatically scan the neck of your pet to check if they have been microchipped as part of their standard procedures.  In either instance, in the event of a tag or microchip not being present your pet will probably end up transported many miles away to a central pound where the chances of finding them start to significantly drop.
