Whilst every dog owner is legally obliged to
ensure that their dog is wearing a collar and identification disc,
thousands of owners have now taken positive steps to ensure their
much-loved companion can also be identified through microchip technology.
Since being introduced in 1989, over
4 million dogs and cats have been microchipped, and this number
continues to grow at an estimated 8,000 registrations per week.
Microchipping is now recognised as
the most effective and secure way of permanently identifying a pet.
A unique identification number is registered to the animal and the
owner's details are placed on a national database.
Sadly, the reality is that of the
many thousands of dogs that go missing each year, it is estimated
that less than half of them are reunited with their owners. Don't
wait until it's too late. Get your dog microchipped and have the
assurance that should he become lost (or be stolen), he is more
likely to be returned to you safe and sound.
What is a microchip?
A microchip is a small electronic device, which is the size of a
grain of rice. The microchip is coded with a unique number that
can be read by a scanner. A microchip works through radio wave frequency.
How is the microchip implanted?
Using a specially designed implanting device the microchip is injected
through a sterile needle under the dog's skin.
Where is the microchip implanted?
In dogs, the microchip is implanted under the skin, between the
Does it hurt?
No anaesthetic is required and the procedure should cause no more
discomfort than a standard vaccination.
How does the microchip stay in place?
Once the microchip has been inserted, the dog's body tissue surrounding
the microchip attaches itself, preventing movement of the chip.
Why does the body not reject the
The microchip is encased in the same material (bio-compatible glass)
that is used in human pacemakers. The microchip and the implanting
equipment are sterilised before use, so that the dog's body does
not reject the microchip.
How is the identification number
Microchips work when a scanner is passed over them. This is because
the scanner produces low frequency radio waves that passively activate
the microchip, allowing the unique number to be read.
Who has a scanner?
It is estimated that there are currently over 10,000 scanners in
use throughout the UK. These can be found at most veterinary practices,
Local Authorities and animal welfare groups. Local Authorities and
animal welfare groups use scanners to check stray dogs to see if
they have been microchipped. If the dog has been microchipped he
can then be returned to the owner easily and quickly.
How are the owners traced?
If an animal is found to have a microchip, the Local Authority,
vet or animal welfare organisation contacts a national database
to find the owner's details. The owner then can be contacted and
reunited with their dog. There are several databases in the UK.
Your registration document will tell you which database has your
dog registered and their contact details. If you need to make any
changes to your dogs registered details , such as moving house,
you should contact yoour database operator. Owners of microchip
scanners have special access to the databases to allow them to contact
you if they find your dog.
Where can I get my dog microchipped?
Most veterinary practices in the UK can microchip your dog, along
with a growing number of Local Authorities and animal welfare groups.
City Dogs Homes can provides microchipping service at our Rehoming
Centre; please contact directly to book a mutually convenient time.
