my bitch is due a booster around the time i hopefully will be having pups from her she will either be just a couple of weeks into pregnancy if her season is on time, do you think it will be safe enough to give her the booster or should i just leave it till the pups are born and weaned, i can't remember if i read somewhere that it had caused pregnancies to abort when given the booster not sure if i read it or just a rumour so thought i would ask anyone had a booster done when bitch in whelp
