Are Microchips Safe for Your Dog?

Modern technology has sometimes overstepped the boundaries of safety and we have to consider if it is an intrusion as well as a health hazard for pets. 

Microchips are in everything today, they are in portable telephones, computers, coffee machines and even in your toaster.


Microchips are embedded into your dog’s skin by a veterinarian with a syringe which is a hollow needle and a plunger which pierces the skin and delivers the chip.   Usually a microchip is placed into the skin beneath the shoulder blades of your dog.


 A scanning machine is needed to identify the codes or numbers in the chip which would then identify your dog.  You also have to be registered with a national registry system where that code would be listed such as the Companion Animal Recovery organization.   If you are not registered, the whole procedure is useless since the codes are not recognized.


A scanner that can scan the chip if your dog gets lost and in a disaster area such as a hurricane where buildings are blown apart these machines may not be entirely accessible.


  tag11.jpgMicrochips are used to identify your pet in case you it gets lost or stolen from you.  I am not convinced this is absolutely necessary in all cases unless you do not live with your dog.  Certainly disasters such as hurricanes or even floods can cause some to believe that microchips are the only way to go for this type of occurrence.   

But when is a dog owner not within the vicinity of their pet, after all do we not live with them and share our homes with our pets?


The case for having your pet micro chipped is up for debate as dog tags have been used for decades without problems.  My dog has her tag on her collar and it never comes loose or falls off since it is securely placed on the ring of her collar.


Proponents of microchips state that this protects your dog, and all dogs should be permanently micro chipped and it’s a good idea but they are probably the same people that sell the scanner machines and the microchips.


I have in my research also found advertisements on the internet that state anyone can microchip a dog or animal, and it does not matter- its just that easy to do.


Take the case of a French Bull Dog named Leon.  It is just one story of a noble pet whose owner was so heartbroken at the death of her dog she dedicated a website to Leon. 


In 2004 Leon was diagnosed with fibroscarcoma (canine cancer) which was located at the site of his microchip implant.  After searching for answers his owner Jeanne dug deeper to find the cause of her dog’s cancer.  The frightening information led to the fact that his dog’s death was man made.


Leon had been vaccinated and micro chipped one year earlier in 2003 and developed this mass at the site of his microchip only one year later.


The veterinarian pathology report  from Italy indicated that for over one hundred years investigators have observed that even wounds and inflammation can cause tumors to develop.


The Federation of European Companion Animal Veterinarian Association has launched a full scale study of adverse reactions to vaccines and microchips.

Studies have shown in laboratory rats implanted with microchips that the rats developed tumors   the time limits are 18 months after implants the animals developed tumors and were surrounded by fibrous tissues which is the dog’s immune system trying to get rid of a foreign object.  In rats this occurred 15 weeks to 2 years after the microchip implant. In cats it can occur 1 month to 3 years after implant. 


Microchips are made from iron, aluminum, bioglasses, magnesium and silicon to name just a few chemicals that make up a chip.  These are not what I want floating around in my dog’s body.  I have to wonder about such advertisements and dire warnings that if your dog is not micro chipped it is less likely to be returned to you if lost or stolen.


How can a stolen dog be returned to you, in any event the thief would be unlikely to give your dog back so that argument doesn’t really make sense.

If your dog is lost – how can a collar and tag be less effective than an imbedded chip which would require a scanner machine that I do not happen to believe is readily available in my home? 


How did we manage to find lost dogs in the last one hundred years and why did tags on collars stop being effective?  Why would anyone put their dog’s health in danger instead of a tag and collar for identification – and just to make it easier for someone to identify a pet.  What would justify putting a dog to risk for the “just in case” mentality that seems to be so persistent today?


Modern technology is not all that its cracked up to be in my opinion but if you do decided to find it is absolutely necessary to microchip your dog, I have included Leon’s website and I want you to read it very carefully before you do decide this very serious danger to your friend.

The chance that you may or may not lose your dog does not outweigh the risk of imbedding your dog with a potentially dangerous object which could cause a premature end to your dog’s life.

    That is not surprising and our condolences to the dog’s owner your neighbor. The micro chipping of dogs or humans for that matter is not necessary. The injecting of a foreign object in the body of a human or a dog will cause the body to reject it. It is totally unnatural and can cause cancer to grow at the site. Thanks for your comment.

    I have one entry against microchips I’d like to add. One of my neighbors had her dog microchipped. Lightning struck her dog at the site on its back where the microchip was implanted. A hole was burned into its back and it had to be put to sleep.

    We had our dog microchipped about 4 years ago when she was a puppy. Her favorite thing to do is sleep. I never gave it much thought until I came across this site. Would it be save to have this chip removed? Could it cause more harm than good? Thanks

    I adpoted a Beagle female a month and a half ago and she soon showed signs of Kenel Caugh and the Pound perscribed antibiotics twice I then adopted a second dog a mini Docshound which was recomended by the vet to have put on antibiotics for the same thing even if I did not notice any sings. I went back to the pound and they perscribe the antibiotics for both pet spronger med then given to the female the first or second time. The female is still looks weak Sleep in eyes alittle red on the whites of the eyes. I am a bit concerned on what to do after reading the microchip new letter could this be a sing that her system could be trying to reject the microchip. Please advise I want to help the Beagle get stronger and healthy. The male Doxie is very strong and does not appear to show any of the signs the beagle has experianced.

    Thank you very much for any informaiton you can provde.
