I had Dillon Micro chipped and the benefits are brilliant.

Ever night when we come home from our walk/run/cycle, I turn the computer on and he always comes and sits by my side. I then put a USB cable up his bum and plug him into the computer.
Once the computer has picked up the new hardware device I am able to log into my system and see exactly what is going on with him:

Heart rate:
> Daily average
> Daily Max
> Daily min
> Weekly, monthly and yearly stats.
> How it changes when he sees me.

Breathe depth:
> Consistency.
> Max intake.
> Breaths per minute average.

Bodily Function Stats:
> Liver mass, capacity and efficiency.
> Kidney balance, capacity and efficiency.
> Lower intestine length, average capacity and throughput.
> Large intestine length, average capacity and throughput.
> Ear balance and noise sensitivity.
> Nose sensitivity, dampness and temperature.
> Hydration levels.
> Nutritional deficiency.
> Muscle mass, functionality and efficiency.
> Faeces consistency, odour and regularity.
> Urine PH level, hormone balance and regularity.

Thought Analysis:
> Regularity of food though.
> Regularity of hydration thought.
> Regularity of hunting cats thought.
> Regularity of REM during sleep.
> Regularity of where owner is.
> Personal opinion of life.
> Personal opinion of owner.
> Personal opinion of self.
> Personal opinion of other individual dog’s bottom odour.
> Attraction to individual dogs.

I can also track him 24/7 with a full GPS system and if he does encounter an emergency he just licks his bottom three times and a full response team will triangulate his position and be on the scene in 30mins max with full emergency dog treats and chews.

As for when he had the “operation” to have the chip installed it was a shock. The needle was approximately 1.4 metres in length and 8cm in circumference (knitting needle size). Initially he panicked like hell and drew blood from every attending person in the operating theatre. The only way we could subdue him was to pepper spray him and then use a 100,000v stun gun in 5sec intervals throughout the operation.
During the operation I have never seen so much blood in all my life eek: and didn’t know that vets kept so many bags for transfusion on site at any one time. The NHS could learn a thing or two.

It was all over in a few days and he’s been no different since. I highly recommend you get your pets micro chipped for your own peace of mind.
