Not safe for longer journeys
I bought this small dog car seat for my puppy. he is now 6 months old. I had a journey of 45 minutes and after about 30 minutes he had tied himself up so badly with the restraints attached to his harness, he was yelping in panic and pain. I stopped the car and it took me ten minutes to carefully detach them from his harness without hurting him. They had wrapped around his leg so tightly he couldn't move. I would not recommend this car seat at all unless you get a separate seat belt harness.
