Sub-par workout-update

I am not to happy with my workout today, but it's my own fault for it being so poor.
Final workout of week 5 and i was really looking forward to it, too bad i tanked it.
Warmed up for 5 minutes and then did my C+P's and pullups, no problem with these, feeling confident still, just have to do my swings.
I start my swings and have done about 25-26 and i hear my dog in the hallway doing something, take a quick look over and she has a schoolbook belonging to my son and she is determined to give it a tour of her intestine. In a perfect fitness world i would ignore any distraction but i had to intervene and so had to stop, maybe 10 seconds max, take it from her and continue on with my swings.
That did me in, could not get going again, i tried, and did get some swings in but it was start and stop for the rest of the time. I don't know now if i would have been able to do it as it was set out in ETK workbook.
On the plus side i don't have to hem and haw about doing the week over again, i will do it over again, and next time i won't have the dog as an excuse, i will succeed/fail next week on my own terms.
Moving on to a different subject i will be starting the warrior diet 3 week fat loss program next week. I've been stuck at 177 for awhile now and i want to lose some of the fat that's left around the middle.

POSTSCRIPT- for my own peace of mind i set my gymboss and did my 50 swings with 10 seconds rest for the full 4 minutes.
This does not change the fact that i will redo the week, i just couldn't go to bed with this bugging me.
