Dog abortions? So terribly sad...those little natural mommie dogs must have felt rotten afterward.
I would vote for birth control of some kind for wild horses, however. Shots that sterilize, perhaps. Horses are being murdered without mercy by the BLM, an outfit I equate with the least civilized savages on the planet — i.e., poachers in Zimbabwe who murdered 300 PROTECTED elephants for their tusks last month, which they sell to the Chinese.
No excuse for cruelty. Ever.
