Dog breeds DNA test

[Cerbhd]

Anyone have any experience of these?
Back story:
Me and the current Mrs cerbhd rescued 2 staffie cross sisters a year and a half ago and out of curiosity have had cheek swab DNA tests done to find their breeds.
1 has come back as over 75 % staffie and nothing else detected and the other as between 37-74% staffie and between 10-20% bull terrier and whippet.
Does this mean they have separate fathers or is it just a test not being accurate enough?
Can 2 dogs from the same litter have different fathers( apologies if a stupid question)
Just to point out that I'm only interested in finding this out for my own sake and not bothered if they are sisters or not. We love them dearly and wouldn't be without them.

I will answer one of the questions

Dogs of the same litter can have different fathers. As I understand it, there are multiple eggs which can be fertilises by different sperm.

Any photos?

thanks, I suspect different fathers is the answer then

Not common, but dogs can have multiple fathers as well.

Google "Chimerism in dogs", for some interesting colouration results!

I have two cats that are brothers but one is most definitely part Ragdoll, not just in looks but in temperament. The other is just a regular non breed specific moggie. It only came to light when taking them both as kittens to the vet for first jabs and me saying I had to moggie cats and the vet putting me straight.
