He had been seen living in a big traffic island in the Midlands, existing like a feral animal meaning he was impossible to catch.
It was only when the police closed the roads around the island and they were able to trap him under a van, an officer recognised Duke as a dog he knew was being abused so he would protect a yard.
Because of this history, Duke has always had issues with people he didn't know, although he has always been great with other dogs.
Fast forward to the last few months and age had suddenly begun to show signs of catching up with him.
Over the dozen years which have passed, he has mellowed out incredibly, but there were signs he was becoming seriously ill.
Weight loss and lethargy, provided a clear signal something wasn't right.
The history he has means he's not a candidate for a trip to the vets for a thorough examination.
He just won't tolerate the hands on, plus any form of anaesthetic may have been too much for his body to take.
The tests we were able to do have pointed towards kidney or liver failure.
There was only one thing I could do. Bring him home.
He has settled incredibly well and loves being around the other dogs, on a sunny day he doesn't want to come in.
He loves lying in front of the fire, even when it's not on, I think he just likes to stretch out and imagine it is.
I have him on a very steady diet, with added supplements to promote liver function and condition, while medication is also clearly helping.
He has gained a noticeable amount of weight and is now very happy to get up and about in the morning.
It's an incredible feeling knowing a dog which has suffered so much abuse and torment over the years, feels as if he can relax at home with me.
I am very proud of him and how he has adapted, whilst knowing our time together may be short.
I intend to make sure he enjoys every single moment of it.
