had her spayed but she’s pregnant part 2 from last night?

thank you to those responses,well those that weren’t jerks,for the ones that don’t know the details let me fill you in,i rescued a choc lab a while back and she was just coming into heat when we had her spayed,it just fell like that we hadn’t noticed till we loaded her up to go,anyway the vet did the surgery or was suposed to,the vet i use was out and there was a fill in vet there,we were told to not let her around male dogs for 2 weeks,we had a sudden death in the family and had to get our neighbors to look after her,we found out later they ended up putting her in the fenced yard with their male choc lab,well i haven’t had to take any of my pets to the vet in a while and i noticed my lab was looking to fat and then noticed her nipples looking weird and called to take her to the vet,couldn’t get a hold of the one i normaly use,so i took her to another vet and yes she’s pregnant,i was PISSED,i have since drove to the old vet’s to deal with them and their no longer their,figures,she has the scar so what the hell did the vet do,i don’t get it when my boston/french bulldog i rescued got parvo the vet was so good,he made it through,anyway,i have found out she isn’t the only animal they messed up,or i’m not the only client the messed over,so now the problem is she’s to far along to abort them,i won’t kill them or put them down once their born,it’s not her,my,or their fault,it’s that dam vet,the new vet said it’s to late to abort so she’s having them,the problem is we don’t know how the boston/frenchie got parvo less than 2 years ago and it’s in the ground now,my house is safe so thats no worry,from what i can find and also the new vet says parvo lives in the ground for 7 years,i don’t want to take chances on the pups and want to give them a chance at life,so what can i do till their old enough to have 2 round of shots,the mom is up to date on shots and is healthy,she is to hyper to come in the house unless i put her in a room by herself or the utility room,but by doing so i’ll be putting my boston/frenchie in danger if she’s a overly protective mother,i can’t make the so called old vet do anything cause their not there and have 12 clients including me suing their asses,so please no jerks and can someone please help or point me in the right direction,is there something to kill the parvo in the ground or will it come through the floor if we build her a pen with a wood floor,i watch my bo/french suffer so much i don’t want to let them go through it,thank you in advance
