Haha. That was amusing. I like writing humour poems.
One thing I think you need is puctuation. If there is no puctuation at the end of the sentence you keep reading it with the next line. There is no break or stop. (I hope that makes sense)...
It was really funny and I like the
'Nasty harnesses for the pink-nosed puppies

I’d rather them swim free like guppies'
That was quite amusing.
Being a woman is hard sometimes. =(
Keep it up. =)

This is not only an extremely funny poem, but an inside view of the life woman down to the last detail. You've written what every woman (well at least the ones I know) hates in a humorous manner. Well done.
