I would think you would get a decent sized show pony type. Maybe 13hh ish. Probably very welshy looking due to the Arab in the mare. Be interesting to see though.
as the mare infleunces the foalie more than the sire I would say you might get something as big maybe a bit smaller than mum ...... only reason I say this is theres a pony locally that was accidently covered by a shetland pony mom 15hhs and dad well the size of a shettie and the pony is 14.3hh
oh and freinds also have an arab mare that was accidently covered by a shettie, had forgotten about him and he is a full up 14.2 also....
regardless agree with others bet it would be a lovely cross.
Thanks, If this foal turns out to be quite nice we might use the same stallion again next time, or they also have a rather nice section c stallion which we could use
I put a post on Arabian Lines as I had no idea of her breeding just her dams name and would you believe they found out for me and put it on all breed pedigree!!
