I know that you aren't supposed to use valbazen on a pregnant doe, but is there a wait period for letting it get out of their system before breeding? We have a nearly 2 year old doe that had liver fluke so we used valbazen even though we typically use herbal dewormers. She wasn't really bad off but wanted to take care of it before we put her in with the buck. She is in heat today but I don't know if I should wait til her next heat cycle? I did 10-10-10 with the dewormer and her last dose was yesterday?! Would it be safe to breed her or should I wait?
