Hello po. I have three shih tzus bago ako mabuntis, and may OB and pedia are both okay naman having them around since unlike other dogs, shih tzus are hypoallergenic. My son is now turning 6 year old and healthy. Since newborn, nakakatabi na sya ng mga dogs ko. Make sure lang na when they're around the baby, may nakabantay pa din para di nila madaganan or dilaan.
