Sue - now that Indy's hair is so short you have a good basis to learn how to trim her yourself, should you wish.
Many of us COlers have learnt how to do it over the years - whilst we might not be upto doing a proper show trim we can still achieve a reasonably presentable pet finish that is better than the one your groomer did ( more natural than the clippers). All the info is on the grooming section. A coat king, a pair of thinners and some straight edged scissors would be enough to get you started - plus a slicker brush if you don't already have one. In the long run you'd save yourself a lot of money and may even come to enjoy doing it.
The beehive would be a good place to start ( I think opinion was unanimous on that - a big thumbs down
) - put on some rubber gloves and get tugging away. Trust me, once you see a nice sleak domed Cocker head ( one of their best features ) you won't miss the topknot at all - if you do, it will always grow back. I was reluctant to remove Jimmy's topknot and didn't give in until he was 20 months old - I soon saw the errror of my ways and wondered whatever I'd been thinking in letting him go round looking like a big haired freak.
