Kitty-sorry you're frustrated- My pup is all potty trained too BUT SOMETIMES he drives me crazy. One thing I find strange is that he ALWAYS will have an accident when I bring him home from the vet, groomer, shots. I think it's just a displacement of concentration after being away and tampered with. Maybe you're baby was just outta sorta after having to go so bad and turning into SUPERDOG and climbing the whelping box! Maybe she was just lonley as well (no humans-no YOU!)
It really sounds like you just had a frustrating day, I'm sorry!!! Tomorrow will be better- these potty problems sometimes happen- even to trained dogs! I'm glad all the puppies were okay though- that's what is most i mportant!
Have a better rest of the day Kitty!!
