Well, Frankie’s dogs were outside and not in the home, where they would be able to attack an intruder. I’m assuming they knew the dogs at CR1’s because of the long relationship between JW & HMR, as well as the relationship between the two families. AFAIK, there were no dogs present at Dana’s.
Kenny’s dog is the odd one out because he was in a small camper and the dog had to be held back when LE arrived. I suppose the Wags could’ve known KR’s dog as well. I guess it just seems odd the dog wouldn’t alert him of an intruder in the early morning hours, unless of course KR was awake and let them in. I really don’t know. All JMHO.
A while back, someone here suggested that JW or his brother, etc. might visit Kenny's camper during the day while he was at work to make friends with the dog. Bring it some treats, etc. The W's grew up around animals, might know how to befriend guard dogs. Just a thought. It made sense to me.
