I am hearing of many same stud dogs where there are multiple litters with juvenile pyoderma- puppy strangles. It is Genetic in many instances. Watch ur bitch line and the stud dog line. Do not be afraid to ask the stud dog owner if there are other cases of it before you breed.

Mine began neurological for weeks then turned into Puppy Strangles at 3 months with my 2 keeping boys. Now to see if they are sterile from the steroids for months.
