What do you mean by 'poodle clip'? She has definitely NOT gotten a poodle cut at all by any of those groomers...otherwise you would have wound up with clean feet and face on her
What you have been getting is most likely, what is commonly called, a "puppy cut", one length all over...with the bichon head, and tail left. If you want her left in a traditional Bichon trim, you need to specify...perhaps, tell them not to take any length off, yet, either. Or tell them to scissor her all over, NOT shave her. If they shudder when you ask them to scissor, take her away fast!!!
Remember what I told you about the texture of her coat, and getting it even? this can be difficult for the best groomer, so don't be too harsh... I thought the last time you had her done wasn't too bad, aside from her head wasn't all that 'finished' in appearance...but maybe your girl was squirmy that day...alot of factors go into a groom job, so really, you need to give a groomer atleast 2 chances unless they did something terrible, like injure it and not tell you, or do something totally opposite of what you said (like shave it's feet and face, when you told them to leave it).
Your groom job isn't all that bad though, either...although, all you did was a puppy cut too...Lol...looks like you just need to brush the coat up, reclip, and rebrush, and rescissor any missed areas, as well as tidy up the head. The head, well, there is no way to really 'perfect' that, except to practice, practice, practice...you want a nice rounded appearance overall, with the appearance of her peering out through a 'mask'...meaning you don't want to clear too much hair away from her eye area. Clean her ears out good, and pluck any ear hair out of the ear canal using an ear powder; I finish off with ear plucking, because then I am sending the dog home with nice dry ears.
