She's acting relaxed now feeding her pups. I'll feel on her to see if I can feel anything odd
Yeah I'd palpate her real good. Usually you can go off of momma's behavior as a good indicator. If she's settled, feeding and tending to pups, and isn't breathing labored still or acting restless, she should be fine. Really the only way to be 110% sure would be to take her in and have a vet check her out, but I wouldn't think that nessecary in this case, in my opinion. Those are gonna be three PUDGY pups though gettin all that milk to themselves! lol
