My dog seems to like rolling around in other dog crap, horse crap and cow pats!

Its happened loads of times recently now and its getting beyond a joke!

She seems to rub her face and ears in it and tries to get it all over her body as much as she can. Why she'd actually choose to do this is beyond me!

Anyone know why she's doing this as i really need to try and stop her doing it. It bloody stinks and its costing me a bloody fortune in shampoo!

Cheers.
