"There are plenty of smaller, Ammy friendly WB sires, so I’m always confused by comments such as seen here.
I wouldn’t hesitate to breed a TB mare to a Welsh, but I’d focus on a lovely WB for this mare. Especially since you’re already breeding your TB mare to Welsh."
LOL, well that’s usually my response when someone discusses breeding a welsh cob mare to something outside the breed…I personally think it’s a waste of good horseflesh and would rather see her (assuming she’s worth breeding) to another welsh cob; but, I love the breed.
Having said that though, my (actually my daughter’s stallion but I still retain breeding rights
stallion puts lovely temperaments on his get. They are level headed and he was so easy to train. As long as the mare is well put together, has a good disposition and she is of similar type I wouldn’t hesitate to breed him with the intent to keep the offspring regardless of the other breed (the only exception to that rule is I wouldn’t breed him to something gaited - just not my thing) because his offspring have been so darn much fun. I have turned away a mare owner with two trak x arab mares and another with a dutch mare because of the mares’ dispositions. So it’s not all one-sided when making breeding decisions. If the OP’s mare is nice and she believes the cross would be well put together, sounds like the cross would be one to risk.
