Over the years
Delia - TB - had to have fronts on even when not in work
Fleur - Hann x TB Had just fronts on and then went to no shoes
Cairo - Clydesdale - taking his shoes off was the best thing - no more thrush. Did need shoes on the first summer, then just fronts for 16 weeks of summer and then never shoed again.
Jemima - gypsy cob - feet like iron, no shoes
Farra - Clydesdale - came with shoes, immediately taken off and never needed them again
Chancer - Gypsy Cob - never had shoes.
I feed only fibre, plus linseed, brewers yeast and black sunflower seeds. In summer I use Kevin Bacon when it turns hot and dry. Trimmed every 6 - 8 weeks depending how how feet look.
