Trimming a poodle is fairly straightforward and can probably be accomplished more easily if you spread a sheet on the floor and sit down with your dog while trimming.  Remember patience is it’s own reward here.  I can trim Peppy in less than an hour after he has been bathed and brushed out, however, when I first started it took over three hours.  Take your time go slow, give lots of treats and words of praise.  I know you can do this.  After about three times of trimming I’ll bet your dog will look better than he does when he comes from the groomer’s.
