There is no average. Most of the dogs look completely different. That would be the problem with designer mutts. No one can guarantee if it would look more like a poodle, a cocker spaniel, or an alien baby. Some can be cute, and some border on the side of alien life. This is because they aren't a breed and can't be bred with each other to make a breed standard. So you would have to google or go to petfinder and look at as many pics as you can find so you can see how very different it may look.
Go to www.dogster.com and on the bar at the left there is a ADVANCED SEARCH..click on that ....then for the breed type/ types there are to bars. Pick COCKER SPAINEL and TOY POODLE. Then scroll down to the bottom and click OK....then it should give you ppls. Hope this works.
