Hiya the best bet is to contact who you last sold him to and conduct a serch there and on the way youll probley find leads that will take you straight to him.
The other alternative is eather a horse magaziene in the collom traceing horses or in the classfield and see what results that brings.
I will say this don't give up finding your horse will feel like a lottery win beleave me it is.
Ok ill start here im michael and the girlfrend who passed on is vanessa.
She sold her pony tammy and the woman did not pay her the full amount.
She had 5 others and could not look after them so tammy was sold on and sold on again.
3 years down the line I said at vanessas grave side I would find her mare if she was alive or passed so I did.
I went to the first yard were she sold tammy and it brought back memorys and he directed me to another yard.
I went there and got a few more leads but no tammy thay said theres a cremello in a yard down the road.
So I investigated and in the feild it looked like her so I left a not with my name and cell number.
3 days went by and her owner rang me and we chatted and I got invited over.
I took papers pictures over o boy it was tammy she was owned by claire and her 2 daughters loran and sophy.
We chatted and I gave her tammys history and tammy was very fizzy and she was an x princephillip cup pony for mounted games it made sence to claire.
Tammy sufferd a fractured shoulder and bounced back with vetanary treatment and claires loveing care as she sustained a sevear kicking from another horse.
I brought my sulky down and tought loran and sophy how to drive claire could not beleave it in what she could do.
I went to vanessas grave and said I have found your baby I said to claire I know you and we started chatting.
Claire worked in watford genral hospital and was looking after vanessa whilst she was on a life suport machine tammys fammaly has got bigger.
I asked if tammy needs any thing just ask I also asked that if any thing happend to tammy could I have her cremated and have her ashes put with vanessas.
Time went on and thay were moveing to the south west of england clare loran and sophy had a talk and thay gifted tammy back to me we took tammy to vanessas grave side and brought her to her new home she had a loveley 10 years with me and she was my gilding trickys partner a mach made in heaven.
Tammy passed on nearley 2 years now and me and tricky lost both of our girls from the same fammaly as we are the same to.
