I'm trying to work out how my Trotter (mum, well bred) Appy (dad unregistered but probably a good horse as was put to a very good mare by a good trotter breeder) 2yo is likely to turn out, physically and temperamentally.I know almost nothing about either breed.Are Trotters like TB's, early maturing because they race at two? How about Appy's? He has a TB type head, most Appys I see are coarser. But he is 100% Appy colouring. His ribcage is huge and he is definitely a wide fit for future saddles. Are there any behaviours or physical problems I should watch for? If he is 15 hands or a little taller now, 3 in early May, what would your guess be about how big he will finish? Anything else I should know? Stale mince pie or hard centres from the chocolate box for anyone?
