@jelly2020it's not necessarily a minefield but the combination of two breeds does it make it harder.
For what it's worth, neither labradors or springers are particularly healthy - I think between them they need something like 18 different health tests to be considered 'Fully Health Tested' under the Kennel Club standards.
And those standards (the 18 tests above) don't necessarily cover tests that aren't mandatory but should be done (i.e. Heart tests in Golden Retrievers - not mandatory at all, but no one should breed any Golden Retriever without having those tests done).
People are often very blasé about health tests, but things like hip dysplasia - which springers and labradors are both prone to - can be horribly life-limiting for a dog, and not only that incredibly expensive to manage (we're talking £5K+ per hip in a worst case scenario). And breeding two breeds prone to those issues together does not minimise the risk of those issues occurring - if anything it's probably more likely, as recent RVC research shows (due to the quality of breeders).
There's nothing wrong with the cross, if that is what you want. But you need to be far more mindful about the risk of puppy farms, unscrupulous breeding practices and defective (unhealthy and personality challenging) puppies than you otherwise need to be.
As RedBoxer says, you could adopt - but there is a reason very often why these dogs end up at rescue centres and there are very few Spaniel Aid dogs that are suitable for homes with young children.
