I wouldn’t bother. The ones I have met were all built like train wrecks in conformation and had weird-at-best coats. I would not ask any poorly built puppy with a questionable coat to do something like waterfowl retrieving.
Yes, both parent breeds are retrievers in the same way that both the Jeep Wrangler and the Subaru Forester are all-terrain vehicles. But I wouldn’t build an all-terrain vehicle by welding parts from both together.
The Labrador’s coat works by being hard and straight with a dense undercoat to keep the puppy warm and watertight. The Poodle’s coat works by being soft and curly with no undercoat to keep the dog warm and watertight. A mongrel of the two might end up with no undercoat and a short, soft coat. Or it might end up with a long curly coat and a lot of undercoat that waterlogs without the proper topcoat to protect it.
If you need a hunting dog, then get a purebred from hunting lines of either breed.
