Everything starts with acclimatizing your dog to the existence of the booster seat, although if it has no problems with its doggie bed acclimatizing to the booster seat should be fairly easy. You can start by placing the booster seat inside your home and just allow your pet to sniff it and explore it a little bit. Once your dog has acclimatized to the presence of the booster seat, you can then start putting your pet inside the booster seat. Most pet booster seats have very high sides so your dog may not be able to get in or out. As such you will have to lift your pet and put it inside the dog car seat. Praise your dog for not making a fuss and give it a doggie treat. You can also put some of your dog’s favorite toys inside the pet car seat. The idea is to create an environment where your dog will feel safe, secure, and comfortable.
