I thought they were growing and needed extra rest. I had a female that got very finicky about her food at that age, I think it lasted several months. I eventually changed food and she seemed to like the new brand better, so she started eating again. My dogs like cat poop too, it's really disgusting, but luckily there aren't that many cats around.

Rhiann @ Butlerbullz

cat poop can cause big worm issues in dogs
I would do that first off before anything else.

also on a side note
My male bulldog..not my female he stopped and settled down big time
during all his growth periods.
wander if your bully is in a big growth spurt

but definetly rule out the worms..

might have a bacterial infection from that

He would rarely turn down a good game of chase the ball or tug of war, but now he REALLY has to feel up to it
