They are adorable pups. I hate to say anything or imply anything negative , but have you taken them to the vet to see if they are microchipped? I would be concerned they were stolen , not cared for by whoever stole them , and dumped when they turned out to be a handful.
My purebred puppy was strayed at about 12 weeks old..we had him checked for a microchip , tattoos ..and I checked all the places someone would post about a lost or stolen dog which is how I found this forum.
I'm just pointing out that just because they were in not so great condition it does not mean there is an original owner that is heartbroken somewhere . They could have been either found by a clueless person and then set free again ..or they could have been stolen from someone's home. It is nice of you to care and to take them in...I just know that I slept easier at night knowing mine was not a stolen or lost puppy . At least not from my area ((shrug))
Anyway , best of luck with them. You should check out the other sections about the challenges of raising litter mates together !
