We rescused a cocker a few months ago, and she came to us with very very short hair (totally scalped) because her previous owner hadn't groomed her at all, so she was matted right back to the skin 
Her hair is growing back beautifully now, but DP and I are torn on how to groom her going forward.
She's really small for a cocker, so her belly is quite close to the ground, and we live on a farm. She gets very muddy. Often the mud gets clogged up in her fluffy feet, so at the moment I wash her feet after a walk, and then brush out any dried mud in her coat in the evenings. We haven't reached the full depth of winter yet, so I'm not sure if this will get worse.
We originally thought we would get her cut in Spring, but now I'm wondering if it would be better to just keep her fur shorter all year round. This is DP's preference.
What do you all do? We are new to long haired dogs, so any advice at all would be very gratefully received. She has very fine fur compared to our terrier!
