Pet corrector spray and noise alarm in one pocket, noise and smell alarm in the other pocket (had some bad experiences on walks with both my dogs being attacked in separate incidents so prefer to be forearmed). Oh and some tissues too.

Don't have poo bags or treats in pockets as these are kept in a little fabric bag that covers Cherry's flexi-lead handle.

I can't carry tennis balls in the pocket - he pickpockets them out for when HE thinks its ball time.

Tissues, door key and poo bags.

mine usually consists of poo bags treats, a tennis ball.... then when they are offlead the leads get shoved in there too.

however i noticed the other day when the weather was nice and i didnt need my jacket that there was a distinctive lack of pockets to fit everything in

Tissues , poo bags , house key and mobile phone

Nothing ! I carry a hand bag (shoulder bag) as I have to carry my epipens and they won't fit in a pocket. In my bag I have pizzles, poo bags, wet wipes and toilet roll (Duncan's hairy bum needs a bit of cleaning sometimes ). Keys and purse too.

Vaseline in the left hand jeans pocket, mobile phone in right. Poo bags in both the back jeans pockets and my keys (car/door) in one of them, ALWAYS! I feel naked if I don't have all of these in my pockets. I actually have permanent indentions in the shape of the round Vaseline tub and the mobile in all my jeans pockets.

Ooh-too much information!
We use "nature's toilet paper" (leaves) when necessary but one time I was just grabbing some leaves to wipe Parker's bum when he reversed into me and wiped himself on my trousers! Husband made it worse as he said "never mind at least they are poo-coloured already!" (I prefer to call it beige!).
