Hi Christine, for the terms of the pet passport, the location of said chip has to be stated on the paperwork: "dorsal between scapular". He now has a new UK passport that has the latest location on it :rolleyes:

We chipped Chelsea at 13 weeks and Savannah at 11. Both reacted not unlike a regular injection. It obviously was more of a nip and did bleed a bit more as the needle is bigger - but neither have adverse reactions to injections now because of it. Within seconds it was forgotten.

Neither have moved either:)

I took my younger boy for his - he was 11 weeks old and didn't make a sound. There was no bleeding, nothing. I expected him to howl as he was a wimp, he used to wine if you got hold of him by his scruff but the chip was a doddle. The vet checks the chip whenever we visit to make sure it hasn't moved and is working.

It's reassuring to hear that most dogs cope OK - I suspect I will be the one freaking out, rather than the dog!

I did hear that certain dogs stolen inthe Dorset countryside were left to roam, and thus eventually returned to their owners, if the thieves found them to be chipped.

Hi Im new here!!!I was having my retriever chipped soon but not now! Not if they tend to go south

I have been microchipping now for over 12 months as a non vet. implanter using several different types of chips.
The best implant site ~ according to the literature and research into microchipping cattle is in the skull but clearly this is not practical and the recognised site is between the shoulder baldes at the withers.
The available literature also tells you that the size of the chip affects its chances of moving and there are various different size chips on the market ~ the safest apparently being the smaller ones.
Several of the chips I know of have moved ~ some have moved a considerable distance:-( ~ including one that was implanted in my own dog at Crufts by a representative of Petlog. Some of the chips can move from the implant site to the front of the chest or down the legs in a matter of days.
I dont think the implant technique has a great deal of relevance to the movement of the chip although no doubt the manufacturers would like you to believe that it does. The chip should begin to implant itself under the skin wherever its implanted within hours of being put there. Several factors could affect its implantation ~ rubbing the implant site and the anti migratory surface of the chip to mention only 2.
Without a doubt I'm sure some chips *do* move ~ equally they are capable of failing. Unfortunately there seems little information available as to just how many *do* move and where they moved to.
I'd always suggest that people have their chips checked on a regular basis to ensure they are where they are supposed to be and that they are working.

Welcome to the forum Alyson and thank you for your input
The migration of microchips and there implantation is something that interests me greatly and I must say that it is refreshing to hear a 'chipper' admit that there are problems, without going into sales patter. Do you think that someone somewhere should be keeping records of *things that go wrong*? If you have an hour to spare, you might be interested in reading a debate we had a little while ago about Micro Chipping :D

Hi Leigh,
You can report the movement of chips to the company who manufacture them (vets have a form they can submit to report these things but many never bother to fill them in)~ Its how much of that information the manufacturer will own up to that probably hinders knowing how often they really do move.
Robert Killock ( columnist for Our Dogs) was collecting this sort of info last year ~ I don't know if he is still doing it.
There are problems with both types of ID (chips and tattoo), basically you should weigh up the pros and cons of both before making a decision which to use (or both!)

Totally agree Alyson, there are things for and against both methods it doesn't really matter which form of permanent ID you use, as long as you use something and at the moment at least we have a choice. Personally, I would never have opted for a chip but had no choice in the matter. The dutch vet was recently informed of its migration and seemed to think that it was common for them to move! Luckily, I own a scanner and can keep a regular check on where it has got to now :rolleyes: One advantage to keeping data on migration, would have been to see if there was a 'favoured' location for application, that resulted in less movement. I suppose we will never know.

got my 2 done about 20 months ago and both have moved into the right shoulder, well thats where they were last check about 6 months back.
