I admit I don't get along with my MIL we constantly argue and don't see eye to eye. She has taken DD out for a couple of hours (DD is 4 months old). I was absolutely horrified when I went to put the car seat in my MIL car. It was a total disgusting mess, dog hair everywhere and items all over the place including a bike not tied down. I chose to ignore but what really rattled my cage is that the dog was in the boot. The dog is unpredictable I've seen him pounce on people before admittedly he only has ever grabbed their clothes and not bitten anyone but I still don't like the dog being loose in the car. Should I say something to MIL like suggest that I pay for a dog grate for the car incase the dog decided to jump over and attack my baby?? Or should I just leave it. I'm maybe a little over the top as my sister was bitten by a family friends dog when she was 16, it really made a mess of her face.
