Dapple worries

Here are my females dad and mom. And grandparents on moms side

Dapple dachshunds should never be bred to one another. It is not safe for a dog to inherit two copies of the merle gene. The pups are at high risk of partial or complete blindness and deafness, as well as missing or malformed eyes and ears. Even those that do have their eyes and ears intact at birth and possess sight and/or hearing can lose it as they grow up, and they are very prone to glaucoma and cataracts.

I believe that the major dog clubs will not register the offspring of two dapple dachshunds.

I would discuss this with a vet immediately - you need real medical advice at this point, not rando internet people advice. Terminating the pregnancy should be an option that's on the table especially if it's early days.

This is is not a wait-and-see matter - if both parents are dapple, you can end up with an entire litter of puppies that all are deaf, blind, or deaf-blind, and may also have physical malformations. If you can't or won't terminate the pregnancy, you need a plan in place before birth for how to ensure these high-need dogs are cared for after they're born.

Unfortunately, it doesn't matter how much pigment the parents have. If a puppy inherits two copies of the merle gene (called dapple in dachshunds, but it's the same gene), it can and will prevent a certain amount of pigment cells from developing properly, and if cells related to eye and inner ear development are affected, this can and will damage their vision and hearing.

Every puppy has a one-in-four chance of inheriting two copies of the merle gene. While this may mean exactly 1/4 of the litter is a double dapple, it's possible that all will be, or none. It's impossible to know until they're born, and even then some might need genetic testing to confirm. Not every double-dapple has vision or hearing problems, but the risk is very high, and I would encourage you to get any puppies with a large amount of white coloring vision and hearing tested before you place them in homes, especially if you plan to ask for a price equivalent to other breeders. Of course, any puppies with impairments should not be going for full price, and everything needs to be disclosed to the new owners, even if their deficits are relatively minor. Even at a discount, these puppies may be difficult to place in homes that have experience with special needs dogs, and therefore have a higher than average risk of winding up in the shelter system due to owners not being prepared for the challenges they present. The responsible thing would be to make sure your puppy homes know you will take back any puppy any time and rehome them yourself so they don't have to suffer this fate.

And yes, this litter might not be registerable in the reputable kennel clubs, which means if you plan to breed the offspring, even if they're not double dapple, they will not be 'papered'.

If I were in your situation, terminating the pregnancy is something I'd consider discussing with my vet, and seriously consider if it's safe and possible. I'd also be considering whether I have the ability to keep any puppies born with impairments for longer - possibly much longer - than the typical eight weeks in case I can't find them all homes with the dedication and resources to work with them.
