Looking for a loan pony/companion pony

Hi I'm thinking of looking for a loan pony as a companion and possible ridden lead rein but just a companion would be OK.

I have two very friendly gelding one elderly chap and one 12 yeads old. I'm looking for a pony not to big that can be a lovely friend in the field for when the other is being ridden ect. Also would be looking for one that can be left alone for a short time if needed.
Needs to be a good doer no laminitic ponies as it's a living out private place with shelters etc. It's very quiet and peaceful where we are with around 4 acres of land.

I would consider a possible livery maybe as well.
Needs to be a friendy pony safe with children and good to handle.

Hope to hear from you soon. Read more
