My dog found a piece of chicken one time and similar to that she always goes crazy when we get around that area.
She also got jumped by two chihuahuas near this house and is always super paranoid walking backwards and everything when we get near there only until we get closer to the house with the cats she starts hyper focusing because she knows as soon as we get past the fence she can look to the right and see a fat cat that she stares at intensely. Compared to my other dog next to her who is blissfully ignorant of all things going on around him
My dog once saw another dog kick up the ground after pooping to cover it. She now does it every single time, but didn’t learn it right so she ends up kicking up dirt randomly in other directions for a few seconds.
My uncle had a dog for about 10 years. Took him camping every weekend and would chill out by the truck all day. No issues. One random dog came up and peed on the truck tire once. Dog said “wait what you can do that?” and for the rest of his life pissed on the truck. It was a mindvirus.
I know this hell all too well. My Setter finds a cat hiding in bushes about once a week so every bush within leash range MUST be examined no matter the weather, tension on the leash, or exhaustion level (his or mine).
