How long can I leave a 13 week old BC Alone for? in General Border Collie Discussion Posted March 27, 2019 · Report reply On 3/24/2019 at 9:53 AM, GentleLake said: That usually requires very slow introductions (or re-introductions) beginning with just approaching the car with lots of treats to create positive associations, then getting into the car with out turning the engine, then just sitting in the car idling and gradually working up to 1 minute, 2 minutes in a moving car, etc. all the time will lots of treats and play and not moving on to the next step until she's showing no anxiety with the stage you're at. Sadly, it's highly unlikely you'll be able to achieve that in just 2 or 3 days. You might want to ask your vet for something to settle her stomach for this upcoming trip. Not only will it make this trip less unpleasant for her (and you) but the more negative associations she has with the car, the harder it will be to undo them. We ended up bringing her yesterday and she did FANTASTIC! It was a great confidence builder and she received tons of positive attention from people + was able to see and try new things. I thought she would go right into her kennel and sleep when we got back, but boy was I wrong as she was excited late into the night! lol.
