Tinkers or paranoia

Hehyo, I pass my car 3 times a day, because I have to go with my bitch Gassi. Health-related the car was now 2 weeks. The little one felt sniffed at every car, so also at ours. Now I saw something at the rear which did not look like chance. Did you have that already? Didn’t look in the car now because I had no key but looked normal. Am I just paranoid now?
