No, in fact pine is common and sometimes preferred as bedding for horses.
Shavings from fir and pine are often the main type used for "white shavings" commonly packaged for horses.
Shavings to generally avoid or be cautious about are shavings from hardwoods like maple, some types of oak, and fruit and nut trees, like black walnut in particular.
