If the cow is not in the best of health and condition it could be harmful. Being pregnant and nursing are both a drain on the cow. If she's not thrifty and tends to lose condition in either circumstance, I'd delay rebreeding her.
In a family herd situation, the bull and cows behave differently than they would in a mixed herd or as strangers being introduced to each other. A bull will breed any strange cow that's in heat, at any time. When he's in a stable family herd, with only one bull, he manages his cows. Rebreeding comes at the most natural time.
In my family herd, I've had an extraordinary cow calve just 9 months after her previous calf. She never looked the least bit put out by it. The longest she ever took between calves was 12 months. They came at 10, 9, 10, 12 and 11 months. The guy that has her now breeds her every 15 months, since he's milking her. She's fat as a butterball now.
Dexters seem to be pretty sturdy about keeping their condition up. I just had my bull tested for feed efficiency and he scored very high. Of course, all you had to do was look at my barren pastures and his fat butt to know that, anyway.
