My 2 Cents.......
According to the Wagner's pastor, the Wagner's wept over dogs. And of course they breed dogs.
So there is a strong affinity for dogs and you can see that in the way all the dogs were left alive and uninjured.
But I don't think the Wagner's had to hurry and get the dogs used to them because all the dogs had been familiar with at least Jake for years. According to LM Jake came to his house for all the Holidays and Jake lived with the Rhodens off and on as part of the family.
These dogs would not see him as a threat at all. However, yes they would bark at first but then calm down when they could see and smell who it is.
We know Kenny had one dog, Chris Sr. had 2 that BJM mentioned, and LM mentioned Dana having a dog or dogs. Jake lived with Dana so that takes care of her dogs, Dana lived right next to Chris Sr's home so that would take care of his dogs, and Kenneth lived a few miles down the road from the Flying W Farms so it would be convenient to stop by there and see Brownie.
But did Frankie have a dog? BJM didn't mention it. The dogs are a big clue and always have been. The dogs show that the killers had been around and inside the Rhoden properties.
This is circumstantial evidence, but they left a trail of a lot of circumstantial evidence. Circumstantial evidence builds up and is enough to be convicted on. Finding parts to make a silencer is circumstantial, but with forensic evidence it can become direct evidence.
