To continue the tangent...I have found even fewer reputable, responsible breeders of cross-breeds (as a percentage) who health check, home check and offer to have the puppy back if it doesn't work out than I have of pedigree dogs. The vast majority I have come across are, unfortunately, the type who have jumped onto the "if I cross this dog with this completely uncomplimentary dog it will make a 'funny' name and I can charge hundreds for each pup" bandwagon. I have seen so many odd crosses where the parents are from completely different types - different temperament characteristics, bred for different jobs, have different known health issues - that the only apparent reason for ever crossing them was to get the 'cute' name.
There is also a common misconception (no pun intended) that if you cross two extremes, you will get something in the middle. Genetics doesn't work like that. You are more likely to get a Jack Russell on Chihuahua legs, or a pup that gets all the worst characteristics of both parents and another that gets all the best but no standardisation even within the same litter, let alone different litters. So if the OP's dog is F1 cross, it is impossible to say with certainty that its coat would look like X, because there are several variations possible from a cocker spaniel - poodle cross.
To create a new breed requires patience - this isn't something that would be done in a couple of generations; a clear vision of what the resulting dog's job should be and what it needs to look like to carry out that function, and the self-discipline not to breed from any pups which aren't a step towards that end goal. It does not involve crossing two random dogs.
That's not to say that a) pedigree breeders always got it right; sadly we know from some of the health conditions currently prevalent that that certainly isn't the case or that b) the OP is wildly irresponsible and single-handedly fuelling the trade in unscrupulously bred designer crosses, but not to be aware of the risks, the myths and the realities is to do the dogs a disservice and is one of the reasons so many of them end up in rescue. It is a fact that physically and/or temperamentally unsuitable dogs are being deliberately bred together to produce puppies with a 'quirky, cute' name.
OP, I'm sorry you're not happy with your dog's trim. I echo the suggestions to get a word of mouth recommendation for a good groomer when the next trim is due, and I hope your dog's coat grows back quickly.
