Falling off the poop wagon

Kushi fell off the wagon today, that is, the poop wagon. She hadn't had any accidents since she was 5 months old (almost two months till now). This morning, as usual, we fed her breakfast in her playpen, while we ate breakfast as well. We were watching TV, so we didn't notice when Kushi suddenly stopped eating halfway through her meal (if she stops eating before finishing her meal, then something definitely must be up). She started going poop in her playpen, which she had never done before, and we yelled at her to stop as we ran to her. Once it starts, though, it's way too late. She had even gone poop earlier in the morning. I think from now on, we will feed her after we are done eating, so I can better watch over her.

Also, she is trying out a brand of dog food called Timberwolf Ocean Blue, which is causing her to poop a lot more, both in quantity and number of times, than when she was eating Orijen Puppy. She poops first thing in the morning, twice during her morning walk, once or twice during her evening walk, and sometimes even at night. Others have also noted that their dogs also poop a lot more with the Timberwolf brand. On the other hand, she has not "scooted" her butt (i.e. anal glands full) on the ground since eating the Timberwolf, which she did when eating the Orijen. There is less calories/kg in the Timberwolf than the Orijen, so it's probably a matter of her just eating more Timberwolf to get the same amount of calories as in Orijen (which of course means more poop).
