Yes, this can affect Hazel having all GSD puppies. Because female dogs release multiple eggs when in heat, if they mate with multiple males, there is the possibly that the puppies will have different fathers. Since she had mated with another male, it’s likely her puppies won’t all be GSD. I hope this helps.
